Description
Antiproton annihilation on the bound nucleon allows to study exclusive channels
of mesonic interactions with the target residue. If the hard scale is present
then such interactions should be reduced due to the color transparency (CT).
I will discuss, first, the "golden" channel A(pbar,J/psi)(A-1)^*
for the study of the J/psi dissociation cross section on the nucleon.
Then, the d(pbar,pi^- pi^0)p reaction at large c.m. angle will be addressed.
Predictions for PANDA@FAIR at will be given for nuclear transparency ratios
calculated within the generalized eikonal approximation and quantum diffusion model
of CT.
