Title: Flavor diagonal tensor charges of the nucleon from ( 2 + 1 + 1 )-flavor lattice QCD

Abstract

Here, we present state-of-the-art results for the matrix elements of flavor diagonal tensor operators within the nucleon state. The calculation of the dominant connected contribution is done using 11 ensembles of gauge configurations generated by the MILC Collaboration using the highly improved staggered quark action with 2+1+1 dynamical flavors. The calculation of the disconnected contributions is done using seven (six) ensembles for the strange (light) quarks. These high-statistics simulations allowed us to address various systematic uncertainties. A simultaneous fit in the lattice spacing and the light-quark mass is used to extract the tensor charges in the continuum limit and at M π = 135 MeV. Results for the proton in the ¯¯MS scheme at 2 GeV are g u T = 0.784(28)(10), g d T = –0.204(11)(10) and g s T = –0.0027(16). Implications of these results for constraining the quark electric dipole moments and their contributions to the neutron electric dipole moment are discussed.

FIG. 1 FIG. 1: The data for the unrenormalized disconnected contributions of the light $g^{l,disc}_T$ (top two rows) and strange $g^{ s;disc}_T$ (bottom two rows) quarks. The ground state estimate is given by the solid black line within the gray band. It is obtained as the average over data at multiple $t$more » and $τ$ since no significant variation versus them is observed.« less
