The European Organization for Nuclear Research, CERN, has presented at the LHCP 2015 Conference, held these days in Saint Petersburg (Russia), the sharpest image of the Higgs boson thanks to the combined measurements of the ATLAS and CMS detectors. of the Large Hadron Collider (LHC) during 2011 and 2012.
These data “ offer greater precision on the production and decay of the boson . They also shed light on how it interacts with other particles. All the measured properties are in agreement with the predictions of the standard model and will become the reference for new analyzes in the coming months, which will allow the investigation of new phenomena in physics ”, CERN states in a statement.
” The Higgs boson is a fantastic tool for testing the standard model of particle physics and studying the Brout-Englert-Higgs mechanism that gives mass to particles, ” explains Rolf Heuer, CERN Director General.
Thus, according to CERN scientists, precision measurements of the frequencies of the most common decays of a boson (in 58% of cases) in a quark b and its antiparticle are crucial, since they are directly linked to the force of interaction of the Higgs boson with other elementary particles and their masses .
“The study of its decay is essential to determine the nature of the boson. Any deviation in the measured speeds compared to those predicted by the standard model could call into question the Brout-Englert-Higgs mechanism and possibly open the door to new physics beyond the standard model , ”according to CERN.
