Chiral vortaic effect and neutron asymmetries at NICA O.Rogachevsky, A.Sorin, O.Teryaev (arXiv:1006.1331 and poster presentation HP2010) Both, chiral magnetic effect (CME) and chiral vortaic effect (CVE) belong to the class of effects based on the triangle anomaly in QFT. CVE is a generalization to conserved charges other than the electric one. In case of baryon charge and chemical potential, it should manifest itself by neutron asymmetries, observable at NICA/MPD! Observable: three-particle correlator: In CME case at RHIC: 15 M events were sufficient to establish the effect For demonstrating the CVE, we need 1000 M events, which can be collected at NICA/MPD within a few months of running time!

New members are welcome! Summary The NICA/MPD design passed the phase of concept formulation and is presently under detailed simulation of NICA/MPD parameters development of working project manufacturing and construction of prototypes Physics program will be extended to Nuclotron energy range and call for proposals is announced The Project realization plan foresees a staged construction and commissioning of NICA/MPD elements. The main goal is the NICA/MPD commissioning in 2016. The collaboration around the NICA/MPD is growing. New members are welcome! 23
