What is this in physics?

In connection with physics, sequestering is a proposed means that can be limited by certain particles and forces to further dimensions, prevention or minimize their interaction with the particles and forces that make up the standard model. The idea that is of particular importance for the theory of strings, m-theory and supersymmetry (sussy) has been developed by Lisa Randall and Raman Sundrum theoretical physics. Sequestration can solve some major problems in particle physics. In particular, it offers a solution to what is called the "problem of hierarchy" through the interruption of supersymmetry, avoiding another problem known as "violation of taste". A major problem that such a theory must solve is obvious incompatibility of general relativity with quantum theory and standard model. The theories of strings in which the most basic units of matter such as electrons and quarks are considered extremely small, unidirectional, chain entities, one attempt at such a theory. It has been developed on M-theorii in which the strings can be expandedTwo and three -dimensional "gates" floating in a higher size space known as "in bulk".

In addition to the problems associated with bringing gravity to the picture, there is a problem with the standard model itself, known as the problem of hierarchy. Simply put, the problem of the hierarchy focuses on why the gravitational force is extremely weaker than other natural forces, but also includes the estimated values ​​for the masses of some hypothetical particles transmitting power that differ from the other. One hypothetical particle is assumed that the Higgs particles are relatively light, while it seems that quantum contributions from virtual particles must make extremely more massive, at least without extraordinary fine -tuning. Most physicists consider this very unlikely, so they seek some basic principle to explain the differences.

Supersymmetry theory (SUSY) provides one possible explanation. This states thatFor each fermion-or-particle forming mass-producing a boson-or-transmitting force-transmitted particle, so each particle in the standard model has a super-symmetric partner or "superpartner". Because these superparters have not been observed, it means that symmetry is broken and suggesymmetry exists only in very high energies. According to this theory, the problem of the hierarchy is solved by the fact that the mass contributions of virtual particles and their superparters are removed and removed by apparent discrepaCity in the standard model. However, there is a problem with supersymmetry.

particles creating basic material, such as quarks, come in three generations or "flavors" with different masses. When suggested suppersymmetry, it seems that a number of interactions may occur, some of which would change the tastes of these particles. Since these interactions are not experimentally observed, any theory of supersymmetry must somehow include a mechanism that prevents from preventingwas called the taste of taste.

6 Effects for breaking supersymmetry could be communicated to the standard model of the gate by force transmitting particles that are able to move inside a large but otherwise standard model of the Pčláneky would behave in the same way as in uninterrupted supeSymmetry. The particles in large quantities that could interact both with the gate for breaking symmetry and the standard model of the gate would determine what interactions may occur and can exclude interactions of changing taste that we do not observe. The theory works well if this role plays gravitone-hypertic gravitational force transmitted.

Unlike many other ideas concerning chain theory and M-theorie, it seems to be tested by sequested supersymmetry. It creates predictions for masses of superparters bosone-particles transmitting force-which are in the range of energy that can be achieved by a large Hadron collision (LHC). If these particles are observed LHC, their mass can be adapted to whatLádá. Since 2011, however, experiments at LHC have not been able to detect these superpartners on energy that were expected to appear, which is the result that seems to be an excluded version of the Sus, although not some more complex versions. Even if SESY turns out to be incorrect, the idea of ​​sequestering still has useful applications in terms of other problems and secrets in physics.
