Descrição: We propose a parametrization of the nuclear absorption mechanism relying on the proper time spent by c c ¯ bound states travelling in nuclear matter. Our approach could lead to the extraction of charmonium formation time. It is based on a large amount of proton-nucleus data, from nucleon-nucleon center-of-mass energies s NN = 27 Ge V to s NN = 5.02 Te V , collected in the past 30 years, and for which the main effect on charmonium production must be its absorption by the nuclear matter it crosses.
