22. Chiral vortaic effect and neutron asymmetries at NICA
O.Rogachevsky, A.Sorin, O.Teryaev
(arXiv: 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!

23. 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.
