abstract
The masses of charmonium states immersed in nuclear matter are calculated in LO QCD and in QCD sum rules. While the mass shift for $J/\psi$ are found to be less than -10 MeV, those for the $\chi_{0,1,2}$ and $\psi(3686)$ and $\psi(3770)$ are found to be more than -40 MeV. We investigate the feasibility of observing such mass shifts in the future accelerator project at GSI.

Medium modifications of $1P$-wave charmonia $\chi_{cJ}(1P)$ in cold nuclear matter
χcJ(1P) masses drop by 34–97 MeV in nuclear matter in the QMC+unquenched-loop model, with the D*D̄* loop dominating χc2 and no D-D̄ threshold crossing below 3ρ0.

Absorption of 1$P$-wave heavy charmonium $\chi_{c1}(1P)$ in nuclei
Calculations of excitation functions, momentum spectra, and transparency ratios for χ_c1(1P) on 12C and 184W nuclei demonstrate sensitivity to different absorption cross-section scenarios, proposed for extraction via ...
