Prediction for the transverse momentum distribution of Drell-Yan dileptons at GSI-PANDA
arXiv:hep-ph/0506134 · doi:10.1103/PhysRevD.73.037502
Abstract
We predict the triple differential cross section of the Drell-Yan process (pbar p -> l^+l^-X) in the kinematical regimes relevant for the upcoming PANDA experiment, using a model that accounts for quark virtuality as well as primordial transverse momentum. We find a cross section magnitude of up to 10 nb in the low mass region. A measurement with 10% accuracy is desirable in order to constrain the partonic transverse momentum dispersion and the spectral function width within +-50 MeV and to study their evolution with M and sqrt(s).
