CHICAGO. Hopes on the discovery of a new particle that would change the paradigm of physics vanished when scientists admitted that a big change in the data collected was actually an insignificant change.
The announcement December 2015 on the discovery of a significant fluctuation in the data by two independent groups of scientists working on the Large Hadron Collider (LHC), an accelerator of managed by the European Center for Nuclear Research (CERN), particles had generated great enthusiasm.
This fluctuation, with an energy of 750 gigaelectrovoltios (GeV), would have been six times stronger than the famous boson boson, an elementary particle considered key in the fundamental structure of matter, discovered in 2012.
But after much speculation and several leaks in social networks, scientists announced at the International Conference of Physics of High energy, in Chicago, that in reality, there was no such fluctuation in either experiments.
“the intriguing hint of a possible resonance at 750 GeV decaying into pairs of protons, which led to an interest considerably from the data of 2015, has not reemerged in far more extensive data from 2016, so it seems to be a statistical fluctuation, “said a statement from CERN.
scientists present in the meeting, held every two years, reacted on Twitter to the news even before it was formally announced.
“There will be no announcement of a new particle at # ICHEP2016, but that’s how science works “Fermilab, the main laboratory of physics particularly the United States said. “Basically two experiments at the LHC saw the production of two photons often than expected”, tweeted his Brian part Colquhoun , a particle physicist at the University of Glasgow.
