     "Charmonium (c¯ c) mass in antiproton-nucleus reactions, how the
         in-medium gluon condensate can be measured"


             címmel tartandó szemináriumára.

Kivonat:

  The masses of the low lying charmonium states, namely, the J/Ψ,
  Ψ(3686), and Ψ(3770) are shifted downwards due to the
  second order Stark effect. In p¯+Au collisions at
  6−10~GeV we study their in-medium propagation. The time
  evolution of the spectral functions of these charmonium states is
  studied with a Boltzmann-Uehling-Uhlenbeck (BUU) type
  transport model. We show that their in-medium mass shift can be
  observed in the dilepton spectrum. Therefore, by observing the
  dileptonic decay channel of these low lying charmonium states,
  especially for Ψ(3686), we can gain information about the
  magnitude of the gluon condensate in nuclear matter. This
  measurement could be performed at the upcoming PANDA experiment at
  FAIR.
