Evidence of the Higgs boson at Fermilab

Physicists working on the HyperCP topic at Fermilab (USA) have just confirmed that they can both have initial results on the Higgs boson - the kind of elementary particle that many assumptions claim to take up most of the mass in the Universe. cylinder. However, to confirm this correctly, the Standard School Theory of particle physics (born more than 30 years) may have to give way to the replacement of supersymmetric theory (According to the results just published on Phys. Rev. Lett. 98 (2007) 081802 ).

A major achievement of the Standard School Model is that it unifies the two fundamental forces that are the weak interaction force and the electronic force in a weak, symmetric electromagnetic force unique to high energy. But at low energies, the symmetric weak electromagnetic force theory involves that particles have no mass, which is completely inaccurate. This is the origin of the emergence of the Higgs boson - a particle that can disrupt weak electromagnetic symmetry at low energy. If the current standard model is correct, the Higgs will have a mass between 100 GeV and 1 TeV, which could allow physicists to find it at the Collider 14 TeV Large Hadron accelerator at CERN when it captures Early operation in November 2006.

However, physicists analyzing data from the HyperCP experiment at Fermilab in January 2006 stated that the lab had achieved it for the first time - meaning we might have to benchmark it. be considered an extended model for standard field theory.

This experiment involves bombarding a beam of protons in a fixed beer, resulting in three " events " in which a Sigma + particle decays into a photon and a muon, anti-muon pair. Although 3 "events" are often not significantly related to each other, German Valencia (Iowa State University, USA) assumes that these events can be interpreted as evidence for one. New seeds with masses of 214,3 MeV, they were named " HyperCP seeds ".

Because it is quite light and has a weak probability of interaction, HyperCP will not match the standard field model. However, it can be explained by using the " Next-to-minimal supersymmetric standard model (NMSSM) model." This is one of the supersymmetric models, which tend to explain why the fundamental forces are so different in intensity by assuming 2 or more particles. In the NMSSM model, there are 7 Higgs bosons, and Valencia's group thinks that HyperCP beads may be the lightest of these.

Although more evidence is needed than the three facts about HyperCP to convince other physicists to advance to the NMSSM theory, Valencia has been stimulated by the idea of ​​physics under the school model. current standard. This is not the first time physicists have claimed that the Higgs is another part of the supersymmetry theory. Earlier this year, John Conway and Tommaso Dorigo assumed that a 160 GeV " pump " in Fermilab could be one of the 5 Higgs boson in the more accepted model, the Sup supersymmetric standard model (MSSM).
