Abstract

With data taken by SELEX, which accumulated data during the 1996-1997 fixed target run at Fermilab, we study the production of charmed hadrons on copper and carbon targets with Sigma-, p, pi-, and pi+ beams. Parameterizing the production cross section A^alpha, A being the atomic number, we determine alpha for D+, D0, Ds+, D+(2010), Lambda_c+, and their respective anti-particles, as a function of their transverse momentum pt and scaled longitudinal momentum xF. Within our statistics there is no dependence of alpha on xF for any charm species for the interval 0.1<br />Comment: 8 pages, latex, 9 figures. As accepted by EPJC
