LHC Scientists Find Three Exotic Particles --- and Start Hunting for More - by b0yle
, and since then, scientists and engineers at the CERN research center on the French-Swiss border have been getting ready for today’s resumption of scientific operations.“It’s a magic moment now,” CERN Director-General Fabiola Gianotti said during. “We just had collisions at an unprecedented energy, 13.6 tera-electronvolts, and this opens a new era of exploration at CERN.”
Today’s start of the run comes 10 years and a day after LHC physicists announced their biggest discovery to date:The three new types of subatomic particles, described today during a, aren’t quite Higgs-level revelations. But they do suggest that the LHC is hot on the trail to discover still more previously unseen building blocks of the universe.
LHCb spokesperson Chris Parkes said studying new combinations of quarks “will help theorists develop a unified model of exotic hadrons, the exact nature of which is largely unknown.” Two new tetraquarks are illustrated here as single units of tightly bound quarks. One of the particles is composed of a charm quark, a strange antiquark and an up quark and a down antiquark , and the other is made up of a charm quark, a strange antiquark and an up antiquark and down quark .
