Goal of the present research project is to use effective field theory methods to investigate the behaviour of heavy probes of a hot (and/or dense) plasma. In particular, building on our previous results, we want to develop an effective field theory description for multiscale systems in nonequilibrium evolution using an open quantum system framework. Applications regard the study of the heavy quarkonium evolution in the quark gluon plasma created in the heavy ion experiments, the transport properties, the nuclear modification factor and the thermalization process. Lattice QCD calculations of some transport coefficients are part of the project. These results will impact not only on some of the frontiers of strong interactions but also on the development of quantum field theory out of equilibrium. In future a similar framework may be used to address the propagation of nonrelativistic dark matter pairs (DM) in the early universe.

本研究项目的目标是使用有效的场论方法来研究热(和/或稠密)等离子体的重探针的行为。特别是，基于我们之前的结果，我们希望利用一个开放的量子系统框架，为非平衡演化中的多尺度系统开发一个有效的场论描述。在重离子实验中产生的夸克胶子等离子体中重夸克粒子的演化、输运性质、核修正因子和热化过程的研究等方面都有应用。一些输运系数的格子QCD计算是该项目的一部分。这些结果不仅会对强相互作用的一些前沿产生影响，而且会对非平衡量子场论的发展产生影响。未来，一个类似的框架可能被用来解决非相对论暗物质对(DM)在早期宇宙中的传播问题。
