Baryons

Charmed Baryons
... Charmed baryons are a category of composite particles comprising all baryons made of at least one charm quark ... in the 1970s, a large number of distinct charmed baryon states have been identified ... Observed charmed baryons have masses ranging between 2,300 and 2,700 MeV/c2 ...

Quark Model - Baryons - The Discovery of Colour
... consequence of this classification when it was realized that the spin S = 3⁄2 baryon, the Δ++ required three up quarks with parallel spins and vanishing orbital angular ...

List Of Baryons
... Baryons are the family of composite particle made of three quarks, as opposed to the mesons which are the family of composite particles made of one quark and one antiquark ... Both baryons and mesons are part of the larger particle family comprising all particles made of quarks – the hadron ... The term baryon is derived from the Greek "βαρύς" (barys), meaning "heavy", because at the time of their naming it was believed that baryons were characterized ...

Heavy Baryon Chiral Perturbation Theory
... Heavy Baryon Chiral Perturbation Theory (HBChPT) is an effective quantum field theory used to describe the interactions of pions and nucleons/baryons ... theory one would also like to describe the interactions of baryons with pions ... Because the baryons are much heavier than the pions, HBChPT rests on the use of a nonrelativistic description of baryons compared to that of the pions ...
