We report recent STAR results on searching for the Chiral Magnetic Effect via measurements of gamma correlation and k(K) parameter for charged hadrons and identified particle pairs (pi pi, pK, pi K, pp, p pi) in Au+Au collisions at 200 GeV. We compare the k(K) parameters with expectations from the AMPT simulations. Sizable gamma correlations for charged hadrons, using Time Projection Chamber event plane, in p+Au and d+Au 200 GeV have been observed, and the correlations in these small systems are reduced to near zero when the event planes from forward detectors are used. We will also present our results on the Chiral Magnetic Wave searches from p+Au collisions at 200 GeV.

Abstract
We report recent STAR results on searching for the Chiral Magnetic Effect via measurements of gamma correlation and k(K) parameter for charged hadrons and identified particle pairs (pi pi, pK, pi K, pp, p pi) in Au+Au collisions at 200 GeV. We compare the k(K) parameters with expectations from the AMPT simulations. Sizable gamma correlations for charged hadrons, using Time Projection Chamber event plane, in p+Au and d+Au 200 GeV have been observed, and the correlations in these small systems are reduced to near zero when the event planes from forward detectors are used. We will also present our results on the Chiral Magnetic Wave searches from p+Au collisions at 200 GeV.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
