Proton Spin in Chiral Quark Models


The spin and flavor fractions of constituent quarks in the proton are obtained from their chiral fluctuations involving Goldstone bosons. SU(3) breaking suggested by the mass difference between the strange and up, down quarks is included, and this improves the agreement with the data markedly. PACS numbers: 11.30.Rd, 12.39.Fe, 14.20.Dh
