One answer to questions about the quality of the Higgs boson

I will give a comical but popular explanation first, and then a more rigorous explanation.

Comic-style explanation: When the Higgs field is full of vacuum, like syrup, all particles that feel the viscosity of the syrup can't run fast. The particle corresponding to the Higgs field will also feel the viscosity of the syrup and can't run fast. But this is indeed a comical explanation, because syrup is dissipative, that is to say, particles move energy in it, which is different from particles in Newtonian mechanics. Particles in Newton particles meet Newton's first law and will not be lost energy.

Then I give a more rigorous explanation.

The Higgs field is like a photon field in some sense, there is more than one. The photon field is an electromagnetic field, which is oriented in space, and the Higgs field is oriented in an "internal space". When the electromagnetic field is not zero, its orientation destroys the rotational invariance of space. When the Higgs field is not zero, its orientation in the internal space destroys a symmetry.

There are four Higgs fields in the standard model. When the Higgs field destroys symmetry, a particle moves in this field and radiates and absorbs the field, just as a charged particle moves in an electric field and radiates and absorbs the electric field. The latter result is that the charged particles accelerate in the electric field, but the Higgs field is different from the electric field, so the particles coupled with the Higgs field radiate and absorb the Higgs field and become qualitative.

Photons and gluons producing strong interactions remain zero mass because they are not directly coupled to Higgs, just as uncharged particles do not accelerate in an electric field.

In addition, in the standard model, four Higgs fields have corresponding particles. Three of these particles are eaten by the intermediate boson coupled to the Higgs field, and the intermediate boson becomes heavier. (A more technical image is that before the intermediate boson eats the Higgs field, each particle has only two degrees of freedom, also like a photon, with two polarizations. After eating the Higgs field, each particle There are three degrees of freedom, which are characteristic of mass vector particles.)

After three Higgs particles are eaten, the remaining one is of mass

Turning on the computer and making coffee, Li Miao began to "cultivate" one acre of three points on her blog. It took him several hours to update the article every two days, and every day to take time to reply to netizens' messages, it has become his normal life.

Li Miao is a researcher at the Institute of Theoretical Physics, Chinese Academy of Sciences. On July 1 last year, he started his blog life with the words "Gossip Begins." In just one year, a total of 150,000 people have visited his blog "Gossip Physics".

Here, there is his latest research and thinking, there is a follow-up of the latest progress in the discipline, and there are many small talks related or unrelated to physics. Shocking scientific terms such as "string theory", "dark matter", "supersymmetry", and "human principle" can be found everywhere.

However, if you take a closer look, you will find that Li Miao's blog, although advanced, is talking about physics in a lively and interesting tone, and will not refuse to be a layman. In an article called "Weaker, Darker, and Beautiful," he talked about Lin Daiyu's ill-conditioned beauty, saying "gravity is the weakest force in the world", and this is exactly his research experience.

He used the famous lines in the movie "Big Wrist" to ridicule string theory research with students: "Be sure to choose the longest article to read ... It takes one week to read the introduction, and there are not a hundred students who are scared to death. Fifty, some are frightened by propositions, some are frightened by theorems. If you are frightened by lemmas, you are embarrassed to say hello ... So, our slogan for superstrings is not to be the best but to be the longest. . "

He had wanted to write a "History of Alternative String Music", but only completed a poetic beginning: "In ancient times there was a man with a moustache ... the fantasy light stopped when he was 16 years old, and he was 26 years old when he realized that In contrast, it was said that he was pushing a stroller on a small road in Burr at that time ... He worked tirelessly until the gray hair turned gray, which did not move his busy colleagues. The wealth of quantum theory allowed each of them to share one. Spoon tasting ... "

As you can see, Li Miao basically has to answer the questions. Sometimes it's a problem, and there are several rounds of arguments. Once, a physics-loving middle school student asked him "the idea of replacing the sky-high universe with a method of changing the speed of light", and he devoted a lot of time to giving patient answers.

The blog made Li Miao quickly become a "star" among many unfamiliar students, peers and science enthusiasts. A colleague joked with him that starting from the premise of theoretical physics, what people think of is He Yan. Now everyone thinks of it, and became a blogger Miao!

"Science blogs" like Li Miao are rare in the huge blog group.

A weekly science reporter wanted to learn about Chinese scientists trends, ideas, and interests by browsing the personal blogs of Chinese scientists. As a result, he found only two Chinese scientists' blogs, one was Li Miao, and the other was Wei Yu, a member of the Chinese Academy of Engineering and former vice minister of education. He lamented that "Chinese scientists who write blogs are rarer than pandas."

Even abroad, the situation is not optimistic. According to the British "Nature" magazine reported on July 3, the Technorati blog search engine based on the number of linked sites in the previous 6 months, and found that only 5 of the top 3,500 blogs were "science blogs."

Here, the definition of a "science blog" is a blog written by a working scientist, and it must be about scientific content, not about his cat or something.

The top ranking is the blog of Paul Myers, a biologist at the University of Minnesota, at 179. He is a master at turning expert opinions into blogs, and is passionate about blogging about liberalism and atheism, and criticizing the negative impact of religion on American culture.

"Sometimes I just outline some basic ideas as I did in class. If I write as a journal contribution, it definitely won't work." He said that writing a blog is like "talking in a bar after an academic conference."

Ranked second to fourth is a group blog called "Panda's Fingers" with the theme of opposing intelligent design, opposing creationism, and discussing evolution; a meteorologist, Stefan Ramstoff (Stefan Rahmstorf) 's blog and 5 physicists' blogs about the changes in the universe.

On September 2 last year, five scientists posted in the third-ranked "RealClimate" on the science blog to discuss "there is a certain correlation between the frequent occurrence of typhoons and hurricane disasters and the climate of global warming". They talked about Hurricane Katrina, which has just swept New Orleans in the United States, with authors' research, analysis, charts, notes and references, and finally reminded people that global warming will make hurricanes more serious in the future. Many people participated in the discussion after the article was published, and so far have received 304 responses.

Ranked fifth is Nick Anthis's most legendary blog. In January of this year, he just started writing blogs. In February, on his own blog, he was the first to expose an important NASA official lied to his graduated school, and later became a "Mingbo" .

According to reports, on the day of the publication of the journal Nature, a total of 2,277 websites linked to the top science blog of Paul Meyers. On the same day, the world's number one blog was "A Chinese actress named Xu Jinglei" with 29,181 links.

There is no exact number that indicates how many of the 46.7 million blogs counted by Technorati's blog search engine were made by scientists. But an intuitive feeling is that for blogs, which are different from conventional communication modes, scientists at the forefront of science do not "cold."

In December of last year, Nature magazine discussed the relationship between scientists and bloggers in the news feature of "Science in the Internet Age". The article quotes a scientist as saying: "Science itself is about the adoption, discovery, and use of new knowledge and technology, and the biggest revolution on the Internet is slipping past us."

Mentioning the reason for the lack of science blogs, Miao Li laughed loudly: "Scientists are more traditional." "Of course this refers to the way of doing things, not the content of work."

He explained that scientists generally speak cautiously. Moreover, they are often worried that their peers will know what they are doing and thinking about, which will put them at a disadvantage in the competition.

"In many organizations, it's dangerous to discuss the progress of work openly with others, let alone in a blog, because it could be taken advantage of by competitors." One biologist complained.

There seems to be a more special reason for Chinese scientists to be unwilling to open blogs. Professor Xing Zhizhong of the Institute of High Energy of the Chinese Academy of Sciences was instructed to participate in the commemoration of the World Year of Physics initiated by Fermi Laboratories early last year.

When saying goodbye to netizens, he told his last thoughts: "The official propaganda and reports on high-energy physics in China do not need me to repeat here; I ca nt write the specific deeds of scientists. I'm afraid that it involves taboos in the circle; my own affairs are easier to handle, but too professional and no one is interested, too personal and easy to go astray. "

In addition, an important factor affecting the opening of a scientist's blog is that in the current evaluation criteria, the performance of a scientist depends on how many papers he has published in important academic journals, not on his own blog. How many posts have been posted.

Top-level "Kobo" Meyers acknowledges that as a formal, archiveable document, standard scientific papers are irreplaceable and they are the main work of scientists. However, they are static and have significant limitations.

"Describe your dissertation on your blog, wait a minute, something different always happens. Those who are far away from your usual social circle start to think about the topic of your dissertation, and they often come up with interesting points." He said.

Feng Yan, a young scientist working at the Southern European Observatory, is a proponent of this view. He said in an article entitled "Pros and Cons of the Researcher BLOG" that you write your ideas and learning experiences on your blog. Maybe some of the readers will help you find the mistakes, others' comments may inspire you, and you may even find collaborators.

Li Miao used her own personal experience to explain the benefits of blogging. In January of this year, he learned about the latest research progress on "string theory" on the blog of a Harvard professor, and immediately asked a few students to invest their energy to see if they could go further on this result. Students have now published 3 papers accordingly.

From a reader's point of view, Li Miao likens blogging to cultural fast food, "more trendy than McDonald's McDonald's." He believes that reading a science blog allows you to easily access specialized information, just like eating fast food.

What makes Miao even more important is that they can interact with students through blogs, guide students to think about some problems in the discussion, and learn how they learn.

Feng Yan noticed the "public access" feature of science blogs. He believes that when an academic paper is published in an academic journal, perhaps only dozens or even "comrades" will read it. Ordinary people will not consult academic journals because they want to know a certain knowledge, but if it is described on a blog Your own research progress will make your expertise serve the society and understand, but also let the public know you and your work. For example, majors such as politics, economics, public health, and meteorology can make a difference in this area.

An American epidemiologist writes one or two short articles every day on his public health blog entitled "Effectiveness Measurement" using the "awe" screen name, which has now attracted a wide range of readers group. "There are about 1,500 visitors a day." He said, "If someone tells me that I can go to the lecture hall every day to give some opinions, and 1500 people come to listen, I will be very satisfied-1500, which is the number two in many professional magazines Oh! "

Unfortunately, for most scientists, blogs are still not attractive enough to allow them to be a little distracted from their actual work. This may be the reason why too few blogs are cited by scientists.
