Found traces of the existence of a superheavy boson

Physicists who work on the ATLAS and CMS detectors of the Large Hadron Collider have found traces of the existence of a superheavy boson.

In December 2015, rumors began to circulate on social networks and microblogs that the LHC was able to detect traces of the “new physics” in the form of a superheavy boson, whose decay produces pairs of photons with a total energy of 750 gigaelectronvolts.

For comparison, the Higgs boson has a mass of 126 GeV, and the top quark, the heaviest elementary particle, weighs 173 GeV, which is four times less than the mass of the particle that produced the photons.

Many theories suggest the existence of superheavy particles that can decay into pairs of Higgs bosons. This role can be claimed by both heavy analogues of the Higgs boson and other bosons. Until recently, we could not find any evidence of their existence.

Research text
Physicists used neural network algorithms to look for particle decay chains involving Higgs boson pairs, tau leptons and particles with heavy adorable quarks in their composition.

Some modifications of the Standard Model – the theory that describes most of the interactions of all elementary particles known to science – suggest that these processes may hide traces of superheavy analogues of the Higgs boson and other carriers of fundamental interactions that do not fit into the modern ideas of scientists.

It turned out that there were almost five times more decays involving pairs of Higgs bosons than the Standard Model says. The authors of the new work attributed this to the decays of superheavy particles, which were about eight times heavier than the already discovered Higgs boson.

So far, this is not absolute proof of the existence of a superheavy boson, but only hints of it, so physicists are planning to accumulate more data in order to draw long-term conclusions.
