Hadronic Scattering of Charm Mesons

Abstract
The scattering cross sections of charm mesons with hadrons such as pion, rho meson and nucleon are studied in an effective Lagrangian. In heavy ion collisions, rescattering of produced charm mesons by hadrons affects both their transverse mass spectra and the invariant mass spectrum of dileptons resulting from their decays. These effects are estimated for heavy ion collisions at SPS energies and are found to be significant.
