In 2013 the researchers at the Large Hadron Collider (LHC) announced the discovery of the Higgs boson and that represented a huge scientific breakthrough. Since then, however, scientists are struggling to learn more about Higgs boson’s behavior. Now, during one of the experiments, Higgs boson was observed again only that, this time, it was accompanied by a top quark and an antitop quark, as Live Science reported.
As explained in a statement issued by the European Organization for Nuclear Research (CERN), the scientific body that conducts the LHC, one of the greatest puzzles of particle physics is the great discrepancies in the masses of fermions, the constituent particles of matter. Scientists speculate that the Higgs boson, through its involvement in producing the universe’s mass (as the Living Science explained earlier), might be the answer to that puzzle.
Higgs boson was observed again at Large Hadron Collider, this time alongside a top quark and an antitop quark
The Compact Muon Solenoid (CMS) and the Toroidal LHC Apparatus (ATLAS), two distinct experiments, both noticed a decline that disclosed that the Higgs ” couples ” very tightly ” with the ultra-heavy top quark, indicating a strong bond between the two particles. That outcome aligns with that predicted behavior made by physicists. The presence of an antitop quark has also been noticed.
“These new calculations give a strong indication that the Higgs boson plays a key role in the high mass value of the top quark. While this is certainly a key feature of the Standard Model, this is the first time it has been verified experimentally with overwhelming significance,” explained Karl Jakobs, a representative for Large Hadron Collider’s ATLAS.
These new outcomes, which have been reported yesterday, June 4th, in the Physical Review Letters journal, do not constitute a solitary observation on Higgs boson relationship with other particles such as top quark and antitop quark, but the faint indications of many observations, compiled before the scientists obtained sufficient data to be certain of what they had seen.
