Description

The chiral constituent quark model ($\chi$CQM) is known to provide a satisfactory explanation of the proton spin and related issues in the nonperturbative regime. It has been extended to understand the effects of nonperturbatively generated ``quark sea'' to determine the flavor structure of the octet baryons. In particular, we have calculated the sea quark distribution functions, quark sea asymmetries, meson-nucleon sigma terms which have large contributions from the quark sea and are greatly affected by SU(3) symmetry breaking. Our results show that chiral symmetry breaking and SU(3) symmetry breaking play an important role in understanding the flavor structure of the octet baryons.
