AbstractAbstract

[en] The dimuon production in 200 GeV/nucleon oxygen-uranium interactions is studied by the NA38 Collaboration. The production of J/Ψ, correlated with the transverse energy ET, is investigated and compared to the continuum, as a function of the dimuon mass M and transverse momentum PT. A value of 0.64±0.06 is found for the ratio (Ψ/continuum at high ET)/(Ψ/continuum at low ET), from which the J/Ψ relative suppression can be extracted. This suppression is enhanced at low PT.
