The Phi meson in nuclear matter from dilepton and decays

Gubler, P. 

While the meson vacuum properties, such as mass and width, are well known, it is not clear how these properties will change once it is put in a dense environment such as nuclear matter. Theoretically, many works have been conducted with the aim of studying the meson in nuclear matter. Connecting theoretical results with experimental measurements is, however, not a trivial task, as the meson in nuclear matter is usually produced in relatively high-energy pA reactions, which are generally non-equilibrium processes. In this presentation I will report on an ongoing project, attempting to simulate pA reactions in which the meson is produced in nuclei, making use of a transport approach. Results of simulations of 12 GeV/30 GeV p+C and p+Cu reactions will be presented and comparisons between obtained dilepton spectra and experimental data of the E325 experiment at KEK will be made.
