The flavor dependence of the naive time reversal odd ("T-odd") Boer-Mulders and Sivers parton distribution functions as well as the "T-even" but chiral odd function are explored in the spectator framework. These transverse momentum dependent parton distribution functions are of significance for the analysis of azimuthal asymmetries in semi-inclusive deep inelastic scattering. In this context we also consider the Collins fragmentation function . With this input, we calculate the leading twist unpolarized cos(2ɸ) asymmetry, and sin(2ɸ) single spin asymmetry for a longitudinally polarized target in semi-inclusive deep inelastic scattering.
