Lijuan Ruan, tenured physicist at physics department of Brookhaven National
Laboratory (BNL). She obtained PhD in high energy nuclear physics from
University of Science and Technology (USTC) in 2005 and Bachelor of Science
from USTC in 2000. She did postdoctoral research at Lawrence Berkeley
National Laboratory during 2005-2007. Then she worked as Goldhaber Fellow,
Associate Physicist, Physicist from 2007 to 2015 at BNL. She became Tenured
Physicist of BNL in 2015. She has been working on STAR experiment at RHIC
since 2000, and her research focus over the past years has been on the
experimental study of relativistic heavy ion collisions, with a goal of
understanding the bulk properties of strongly-interacting matter under extreme
conditions.
Abstract:
The Electro-Magnetic probes have been widely used to study the fundamental
properties of hot, dense medium created in heavy ion collisions. Quarkonia
through dileptonic decays have been an indicator of the de-confinement while
the dileptons radiated from the hot, dense medium have been used to study
Chiral Symmetry Restoration, the temperature, and lifetime of the medium.
I will review a few interesting observables in heavy ion collisions enabled by
the STAR Time of Flight and Muon Telescope Detector upgrades. In addition, I
will present most-recent STAR results on J/psi and dilepton production in the
very low transverse momentum region (pT<0.2 GeV/c) in peripheral and midperipheral
Au+Au collisions. Physics implications and future perspectives will be
discussed.
