Hadronic Scatterings of Charm Mesons and Enhancement of Intermediate Mass Dileptons
Ziwei Lin, C. M. Ko, Bin Zhang
Abstract
The scattering effects of charm mesons by hadrons such as the pion, rho meson and nucleon are studied in an effective Lagrangian, and are found to be important in heavy ion collisions. At the CERN-SPS energies, hadronic rescatterings are shown to harden the charm meson mT spectra, leading to a significant enhancement of the yield of intermediate-mass dimuons from charm meson decays.
