Event-by-Event Charge Separation in Au+Au Collisions at $${\\sqrt{s_{NN}}}$$ = 200 GeV Using AMPT

Abstract

The strong magnetic\xa0field created in non-central heavy-ion collisions induces an electric field parallel/antiparallel\xa0to it. This induced electric field leads to the separation of positively and negatively charged particles along the axis of the magnetic field, the phenomenon is known as Chiral Magnetic effect (CME) [1, 2, 3]. We are reporting the measurement of event-by-event charge separation in Au+Au collisions at \\( {\\sqrt{s_{NN}}}\\) = 200 GeV using AMPT model. Event-by-event charge separation is obtained using Sliding Dumbbell Method (SDM). The three-particle correlator for the AMPT generated events is compared with those obtained by reshuffling the charges of particles in an event.
