The finding of the physicists in The College of Arts and Sciences, is the subject of a forthcoming article, prepared by the Large Hadron Collider beauty (LHCb) Collaboration at CERN in Geneva, Switzerland.

Skwarnicki, a specialist in experimental high-energy physics, said:

“We’ve confirmed the unambiguous observation of a very exotic state—something that looks like a particle composed of two quarks and two anti-quarks. The discovery certainly doesn’t fit the traditional quark model. It may give us a new way of looking at strong-interaction physics.

Some experts argued that Belle’s initial analysis was naïve and prone to arrive at an unjustified conclusion. As a result, many physicists concluded that there was no good evidence to prove this particle was real.

This experiment is the clincher, showing that particles made up of two quarks and two anti-quarks actually exist. There used to be less-clear evidence for the existence of such a particle, with one experiment being questioned by another. Now we know this is an observed structure, instead of some reflection or special feature of the data.”
