Cross-section at CLAS12

Semi-inclusive deep inelastic π⁺ electroproduction has been studied with the CLAS12 detector at Jefferson Laboratory. Data were taken by Run Group A at Hall B of the laboratory using a polarized 10.6 GeV electron beam, interacting with an unpolarized liquid hydrogen target. The collected statistics enable a high-precision study of the Cosφ and Cos2φ azimuthal moments of the unpolarized cross-sections. These azimuthal moments probe the Boer-Mulders function, which describes the net polarization of quarks inside an unpolarized proton, and the Cahn effect, which has a purely kinematic origin. The high statistics data will, for the first time, enable a multidimensional analysis of both moments over a large kinematic range of Q², y, z, and P_T. We will present the status of this ongoing analysis, including the multidimensional unfolding procedures used for acceptance corrections.
