  应兰州大学核科学与技术学院Santosh Kumar Das副教授邀请,印度Calcutta大学Sabyasachi Ghosh博士,将于4月18日到28日来我校访问,并进行学术交流活动。

  报告题目:Probing the hot QCD Matter by electromagnetic probes
  报告人:Sabyasachi Ghosh

  地点:医学校区核学楼321

报告摘要:

   It is believed that at a few microseconds after the Big Bang, the universe was in the states of quark gluon plasma, whose temperatures are much larger than the temperature of Sun. The experiments of heavy ion collisions like RHIC at BNL, USA and LHC at CERN, Switzerland have successfully produced this artificial baby universe, whose temperature is of the order of trillion degree Kelvin – a highest manmade temperature till now. Our studies are focus on this high temperature state by investigating its in-medium spectral and transport responses, where quantum field theory at finite temperature is used as a main mathematical tool. The investigation on spectral responses is aimed to solve the longstanding “low mass dileptonenhancement” puzzle, which is believed to be a signature of the QCD medium. On the other hand, the transport response will probe the (nearly) perfect fluid nature of this QCD medium, which is observed in experiments.

报告人简介:

  Sabyasachi Ghosh在2012年于加尔各答回旋加速器研究中心获得物理学博士学位,之后他分别在巴西圣保罗州立大学和印度加尔各答大学从事博士后科研工作,科研工作主要集中在以下领域:
  1.高温下QCD的研究
  2.高能核物理中的唯像研究
  3.高能碰撞中的热场理论

  欢迎广大师生光临!
