30. Mass shift of charmonium states in $\bar p A$ collision

Gyorgy Wolf (Wigner FK)

The masses of the low lying charmonium states, namely, the $J/\Psi$,
$\Psi(3686)$, and $\Psi(3770)$ are shifted downwards due to the
second order Stark effect. In $\bar p + \text{Au}$ 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)...

37. Decay mechanisms in bound state interaction kernels

We study decay channel effects in the spectrum of meson states using covariant Bethe-Salpeter equations (BSEs).. The main goal will be to develop BSE kernels that contain explicit decay mechanisms. This will be first explored in the meson sector where, for example, a kernel suitable to study the rho mesons should contain a ρ− > π + π decay mechanism.​ This will be tackled by including explicit...
