热介质中的夸克偶素解离

Quarkonium dissociation in a thermal medium

Jakub Jankowski, David Blaschke

摘要:

本文研究了在无质量夸克和反夸克等离子体中由于重夸克势的德拜屏蔽而引起的重夸克偶素的莫特效应。通过将轻夸克扇区耦合到由Polyakov圈势驱动的时间规范场中,研究了剩余色关联的影响。这导致夸克偶子态的Mott离解温度的增加,这特别稳定了激发态,但对基态具有边际影响。

英文摘要:

We investigate the Mott effect for heavy quarkonia due to Debye screening of the heavy quark potential in a plasma of massless quarks and antiquarks. The influence of residual color correlation is investigated by coupling the light quark sector to a temporal gauge field driven by the Polyakov loop potential. This leads to an increase of the Mott dissociation temperatures for quarkonia states which stabilizes in particular the excited states, but has marginal effect on the ground states.
