Tensor Charges and their Impact on Physics Beyond the Standard Model

High Energy Physics - Lattice 2021-12-13 v1

Abstract

The nucleon tensor charge, gTg_T, is an important quantity in the search for beyond the Standard Model tensor interactions in neutron and nuclear β\beta-decays as well as the contribution of the quark electric dipole moment (EDM) to the neutron EDM. We present results from the QCDSF/UKQCD/CSSM collaboration for the tensor charge, gTg_T, using lattice QCD methods and the Feynman-Hellmann theorem. We use a flavour symmetry breaking method to systematically approach the physical quark mass using ensembles that span three lattice spacings.
