Title: Historical and New Considerations for Measuring the Chiral
Magnetic Effect

Abstract: 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.
