exotic baryon  

Definition

  • Exotic baryons are a type of hadron (bound states of quarks and gluons) with half-integer spin, but with a quark content different from the three quarks (qqq) present in conventional baryons. An example would be pentaquarks, consisting of four quarks and one antiquark (qqqqq̅). (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Exotic_baryon)
