Abstract
The proton - charged pion correlated emission is studied in
the reactions Au (1.06 AGeV) + Au, Ni (1.06 and 1.93 AGeV) + Ni and
Ni (1.97 AGeV) + Cu within the BUU approach. The associated
invariant mass distributions are shifted to smaller energies with
respect to the free
mass distribution due to
kinematical reasons. We find that the existing and partly conflicting
experimental data do not allow to draw definite conclusions on the
in-medium modification of the
.
