“…It is well known that J/ψ production in hadron-hadron collisions is to a considerable extent due to the production and subsequent decay of higher excited cc states [6]- [8]. We shall here summarize the situation following systematic studies using pion and proton beams at 300 GeV incident energy [8].…”

Abstract:About 40-50 % of the quarkonium ground states J/ψ(1S) and Υ(1S) produced in hadronic collisions originate from the decay of higher excitations. In a hot medium, these higher states are dissociated at lower temperatures than the more tightly bound ground states, leading to a sequential suppression pattern. Using new finite temperature lattice results, we specify the in-medium potential between heavy quarks and determine the dissociation points of different quarkonium states. On the basis of recent CDF data on bottomonium production, we then obtain first predictions for sequential Υ suppression in nuclear collisions.

“…This extrapolation of the rapidity dependence can be used to estimate the total cross section from measurements with limited rapidity coverage and will be used as one method to calculate the total cross section from the present measurement.

We report on charmonium measurements [J/ψ (1S), ψ ′ (2S), and χc (1P)] in p+p collisions at √ s = 200 GeV. We find that the fraction of J/ψ coming from the feed-down decay of ψ ′ and χc in the midrapidity region (|y| < 0.35) is 9.6 ± 2.4% and 32 ± 9%, respectively. We also present the pT and rapidity dependencies of the J/ψ yield measured via dielectron decay at midrapidity (|y| < 0.35) and via dimuon decay at forward rapidity (1.2 < |y| < 2.2). The statistical precision greatly exceeds that reported in our previous publication [Phys. Rev. Lett. 98, 232002 (2007)]. The new results are compared with other experiments and discussed in the context of current charmonium production models.

“…It is known from proton-nucleon and pion-nucleon [ 8] (and, more recently, from electron-proton [ 9]) interactions that a large fraction (about 30%-40%) of the observed J/ψ's are the decay products of higher excited states of cc pairs (ψ ′ , χ). Since the lifetime of these quarkonium states is much larger than the typical life-time of the medium which is produced in the nucleus-nucleus collisions, they decay in the vacuum.…”
