Although predicted for decades, pentaquarks proved surprisingly tricky to discover and some physicists were beginning to suspect that an unknown law of nature prevented their production. Lipkin in 1987 however, the possibility of five-quark particles was identified as early as 1964 when Murray Gell-Mann first postulated the existence of quarks. The name pentaquark was coined by Claude Gignoux et al. 'triquarks'), it is classified as an exotic baryon. Further, because it has five quarks instead of the usual three found in regular baryons (a.k.a. As quarks have a baryon number of (+1/3), and antiquarks of (−1/3), the pentaquark would have a total baryon number of 1 and thus would be a baryon. More resourcesĪnd now for something completely differentĪ pentaquark is a human-made subatomic particle, consisting of four quarks and one antiquark bound together they are not known to occur naturally or exist outside of experiments to create them.
