Beam flavor dependence in the hadroproduction of D{sup {+-}} and D{sub s}{sup {+-}} mesons
Fermilab E769, a fixed-target experiment conducted during the 1987--88 running period, yielded large numbers of charm particles. Through collisions of 250 GeV {pi}{sup {+-}}, K{sup {+-}}, and p on a multifoil target, E769 allows for studies of beam flavor dependence in the hadroproduction of charm. Through the decay modes D{sup +} {yields} K{sup {minus}}{pi}{sup +}{pi}{sup +}, D{sub s}{sup +} {yields} {phi}{pi}{sup +}, and D{sub s}{sup +} {yields} {anti K}{sup *0} K{sup +} (and charge conjugates), the authors have extracted D{sup {+-}} and D{sub s}{sup {+-}} signals for all five beam types. They report preliminary measurements of the beam dependence of the absolute production cross-sections (For Feynman x > 0) of the D{sup {+-}} and D{sub s}{sup {+-}}.
