Proton structure in a light-front quark-diquark model: Collins asymmetry

Abstract

We present model predictions of Collins asymmetries for proton in the SIDIS process for ${\pi }^{+}$ and ${\pi }^{-}$ channels. We use a recently proposed light-front quark-diquark model for proton with the light-front wave functions predicted in soft-wall AdS/QCD. The model predictions are compared with the HERMES and COMPASS data.
