Title: Quarkonium Formation from Uncorrelated Quark-Antiquark Pairs

Title: 从非关联的夸克-反夸克对中形成类夸克物质

Authors:R. L. Thews (University of Arizona)
Abstract: The goal of this section is to assess the possibility that quarkonium production rates may be enhanced in nucleus-nucleus interactions at the LHC relative to that predicted by extrapolation of processes thought to be dominant at lower energy. This enhancement could follow from the effects of incoherent recombination mechanisms involving uncorrelated pairs of heavy quarks and antiquarks which result from multiple pair production. Two different approaches have been considered: statistical hadronization and kinetic formation. Updated predictions relevant to Pb+Pb collisions at the LHC are given.
Abstract: 本节的目标是评估在LHC的核-核相互作用中,夸克偶素产生率是否可能相对于由认为在较低能量下占主导地位的过程外推所预测的值有所增强。 这种增强可能来自于涉及来自多对产生的一对重夸克和反夸克的非相干重组机制的影响。 已经考虑了两种不同的方法:统计强子化和动力学形成。 给出了与LHC的Pb+Pb碰撞相关的更新预测。
Comments: To be published in "Hard Probes in Heavy Ion Collisions at the LHC, CERN report
