  Exciting new scientific opportunities are presented for the PANDA detector at
the High Energy Storage Ring in the redefined $\overline{\text{p}} \text{p}(A)$
collider mode, HESR-C, at the Facility for Antiproton and Ion Research (FAIR)
in Europe. The high luminosity, $L \sim 10^{31}$ cm$^{-2}$ s$^{-1}$, and a wide
range of intermediate and high energies, $\sqrt{s_{\text{NN}}}$ up to 30 GeV
for $\overline{\text{p}} \text{p}(A)$ collisions will allow to explore a wide
range of exciting topics in QCD, including the study of the production of
excited open charm and bottom states, nuclear bound states containing heavy
(anti)quarks, the interplay of hard and soft physics in the dilepton
production, probing short-range correlations in nuclei, and the exploration of
the early, complete $\overline{\text{p}}$-p-annihilation phase, where an
intially pure Yang-Mills gluon plasma is formed.
