Charmed Hadron Production in π p and Kp Collisions and Leading Particle Effect by Constituent Quark-Diquark Cascade Model
Abstract
We investigate the meson, baryon and anti-baryon productions in π p and Kp collisions in terms of a constituent cascade model which includes charm flavour. The constituent diquark in an incident baryon has a tendency to get a large momentum fraction, resulting in considerable difference of subenergies for particle productions from quark-diquark and quark-antiquark chains in a meson-baryon collision. As a consequence, the leading particle effects on D meson productions are expected to be quite different in π+ and π- beams at present accelerator energies.
