摘　　要：We analyze the left-right asymmetry in the semi-inclusive deep inelastic scattering （SIDIS） process using a method where no weighting function are used. Considering all flavor of quarks, we reanalyze the π±production and extend our calculation on the K± production. The predictions on HERMES, COMPASS and JLab kinematics with transversely polarized nucleon target are shown in this paper.We analyze the left-right asymmetry in the semi-inclusive deep inelastic scattering （SIDIS） process using a method where no weighting function are used.
