Flavor-dependent azimuthal modulations in unpolarized SIDIS cross section at HERMES

High Energy Physics - Experiment 2011-07-21 v1

Abstract

The cosϕh\cos\phi_h and cos2ϕh\cos2\phi_h azimuthal modulations of the unpolarized hadron Semi-Inclusive Deep Inelastic Scattering cross section are sensitive to the quark intrinsic transverse momentum and transverse spin. These modulations have been measured at HERMES in a fully differential way by means of a 4-dimensional unfolding procedure to correct for instrumental effects. Results have been extracted for hydrogen and deuterium targets and separately for positively and negatively charged pions and kaons, to access flavor-dependent information about the nucleon internal transverse degrees of freedom.
