Abstract
We analyze flavor-asymmetry in the light-quark sea distribution, using polarized valon framework. The comparison of our obtained results for , and with the GRSV model and recent experimental data from HERMES group indicates a very good agreement with them specially for strange sea quark. Parton orbital angular momentum is also investigated. It is shown that the Q2 evolution of quark and gluon angular momentum is in good agreement with the result which can be obtained in the NLO approximation from helicity sum rule.
