Differential distributions for next-leading-order analyses of charged current neutrino production of charm quarks

Experimental analyses of charged current deep inelastic charm production - as observed through dimuon events in neutrino-iron scattering - measure the strangeness component of the nucleon sea. A complete analysis requires a Monte Carlo simulation to account for experimental detector acceptance effects; therefore, a fully differential theoretical calculation is necessary to provide complete kinematic information. We investigate the theoretical issues involved in calculating these differential distributions at next-leading order (NLO). Numerical results are presented for typical fixed-target kinematics. We present a corresponding FORTRAN code suitable for experimental NLO analysis
