More on p-A collisions
At Large Hadron Collider(LHC) energies the J/ψ production could be even enhanced due to the coalescence of un-correlated c-cbar pairs in the medium which can cause a regeneration. Initial state effects like modifications of the parton distribution functions in the nucleus relative to the nucleon (also known as shadowing) need to be accounted for. The final state effects like nuclear absorption are expected to be practically irrelevant at LHC energies. Studying the pA collisions at LHC energies is henceforth crucial to nail-down/understand the role of initial shadowing effects.
