Running these data through a computer model, they found that they could get the experimental results and model output to agree only when they included two charmonium pentaquarks in the lambda - b decay process — one having a mass of 4.45 gigaelectronvolts (GeV) and the other a mass of 4.38 GeV.

But in July, Takashi Nakano of Osaka University reported that he had detected a pentaquark, a bizarre subatomic particle built from five quarks: two ups, two downs, and an antiquark.

So say physicists working at the CERN laboratory in Geneva, Switzerland, who claim to have found conclusive evidence for the existence of so - called pentaquarks within the debris of high - energy proton collisions.

LHCb collected the data back in 2011 and 2012, but Wilkinson's team held back from announcing their discovery to avoid the fate of those who had made the earlier claims of pentaquark sightings.

The LHCb magnet, shown under construction in 2008, studies bottom quarks and was responsible for revealing the pentaquark.
