Charm production from proton-proton collisions

Abstract

We evaluate the cross sections for charmed hadron production from proton-proton reactions $pp\to {\bar{D}}^{0}p{\Lambda }_c^{+}$ and $pp\to {\bar{D}}^{\ast 0}p{\Lambda }_c^{+}$ using a hadronic Lagrangian. With empirical coupling constants and cutoff parameters in the form factors, sum of their cross sections at center-of-mass energy of 11.5 GeV is about 1 $\mu$b and is comparable to measured inclusive cross section for charmed hadron production from proton-proton reactions. The cross section decreases to about 1 nb at 40 MeV above threshold.
