Researchers at CERN who were able to discover much sought particle, the Higgs boson, announced that it may be found, in fact, two different particles.
The new data revealed by scientists working at the Large Hadron Collider experiments ATLAS and show that it’s about two Higgs bosons, which have a mass very similar, but different.
Unpublished results – which have not been confirmed yet – came after scientists observed an unusual pattern in the original data, which showed that the Higgs decay into two photons more than it should have, according to the theory. Studying the data in detail, researchers found two “peaks” instead of one.
In other words, it seems that there is a Higgs boson with a mass of 123.5 GeV (gigaelectron volts) and one with a mass of 126.6 GeV.
Before the discovery of this particle, scientists have speculated that there may be several types of Higgs bosons, but did not expect the particles have a mass so close. Therefore, most scholars say that it is rather a question of the experiment.
Chance that the result observed due to chance is estimated at 1 in 100, much higher than the standard applied in particle physics, the 1-3500000, because scientists affirm that it is a “discovery”.
Researchers at CERN now trying to find out why there were these unusual results.
