报告摘要：

The Chiral Magnetic Effect (CME) is the generation of electric current induced by local chirality-imbalance in the presence of magnetic field. Heavy ion collisions provide an ideal environment for CME --- as a hot quark-gluon plasma is created with chirality imbalance from gluons topologic fluctuations, and strong magnetic fields is generated in non head-on collisions. In this talk, I will review the current progress of experimental studies of CME and its related phenomena at both RHIC and the LHC, with particular emphasize on the challenge associated with background separation. I will then present a proposal to probe the CME with a pair of new observables that are based on signed balance functions.

报告人简介:

Dr. Aihong Tang received his Ph. D in 2002 from Kent State University, since then he has worked at Brookhaven National Laboratory as a post-doc, assistant and associate scientist, and now, tenured scientist. Dr. Tang's main research interest is the study of the bulk property of the Quark Gluon Plasma created in relativistic heavy ion collisions. That includes a wide range of topics like anisotropic flow and fluctuations, global polarization and spin alignment,  heavy flavor physics and antimatter/exotic search. In particular he is recognized as one of the pioneers in measuring anisotropic flow, as well as in the study of antimatter/exotic particles. Dr. Tang has been a driving force behind many important STAR publications, and his work has accumulated 1800+ citations for those publications alone that Dr. Tang is a principle author.
