Excited charmonium suppression in proton–nucleus collisions as a consequence of comovers
Recent results from proton(deuteron)–nucleus collisions at RHIC and LHC energies have shown an unexpected suppression of excited quarkonium states as compared to their ground states. In particular, stronger suppression of the ψ(2S) relative to the J/ψ has been detected. Similar observations were mad...
