1:25 pm:
Nuclear Physics Seminar in 435 Physics
Speaker: Dr. Rajan Gupta, Los Alamos National Laboratory
Subject: Probing TeV physics using neutron decays and nEDM

This talk will describe the calculations of iso-vector and iso-scalar nucleon charges g_A, g_S and g_T. These quantities are needed to probe new physics in precision experiments of neutron decay and electric dipole moment nEDM. Discussion of lattice QCD results will address systematic uncertainties associated with the lattice volume, lattice spacing, quark mass and renormalization of the novel CP violating operators. I will provide results for the quark electric dipole moment contribution to nEDM and the status of the calculations of the quark chromoelectric dipole moment being calculated by the LANL-RBC-UKQCD collaboration.
