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

Abstract

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 eleven ensembles of gauge configurations generated by the MILC collaboration using the HISQ 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 for the proton in the continuum limit and at MPi = 135 MeV: guT = 0:784(28), gdT= -0:204(11) and gsT= -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.

Axial, scalar, and tensor charges of the nucleon from $2 + 1 + 1$ -flavor lattice QCD

Journal Article Bhattacharya, Tanmoy ; Cirigliano, Vincenzo ; Cohen, Saul D. ; ... - Physical Review D

Here, we present results for the isovector axial, scalar, and tensor charges g^u–d_A, g^u–d_S, and g^u–d_T of the nucleon needed to probe the Standard Model and novel physics. The axial charge is a fundamental parameter describing the weak interactions of nucleons. The scalar and tensor charges probe novel interactions at the TeV scale in neutron and nuclear β-decays, and the flavor-diagonal tensor charges g^u_T, g^d_T, and g^s_T are needed to quantify the contribution of the quark electric dipole moment (EDM) to the neutron EDM.

Nucleon electromagnetic form factors in the continuum limit from ( $2 + 1 + 1$ )-flavor lattice QCD

Journal Article Jang, Yong-Chull ; Gupta, Rajan ; Lin, Huey-Wen ; ... - Physical Review D

We present results for the isovector (p–n) electromagnetic form factors of the nucleon using 11 ensembles of gauge configurations generated by the MILC Collaboration using the highly improved staggered quark action with 2+1+1 dynamical flavors. These ensembles span four lattice spacings a ≈ 0.06, 0.09, 0.12 and 0.15 fm and three values of the light-quark masses corresponding to the pion masses M_π ≈ 135, 225 and 315 MeV. High-statistics estimates using the truncated-solver method allow us to quantify various systematic uncertainties and perform a simultaneous extrapolation in the lattice spacing, lattice volume and light-quark masses. We analyze the Q² dependence of the form factors calculated over the range 0.05 ≲ Q² ≲ 1.4 GeV² using both the model-independent z expansion and the dipole Ansatz. Our final estimates, using the z-expansion fit, for the isovector root-mean-square radius of nucleon are r_E = 0.769(27)(30) fm, r_M = 0.671(48)(76) fm and μ^p–n = 3.939(86)(138) Bohr magneton. The first error is the combined uncertainty from the leading-order analysis, and the second is an estimate of the additional uncertainty due to using the leading-order chiral-continuum-finite-volume fits. The estimates from the dipole Ansatz, r_E = 0.765(11)(8) fm, r_M = 0.704(21)(29) fm an μ^p–n = 3.975(84)(125) Bohr magneton, are consistent with those from the z expansion but with smaller errors. Our analysis highlights three points. First, all our data for form factors from the 11 ensembles and existing lattice data on, or close to, physical mass ensembles from other collaborations collapse more clearly onto a single curve when plotted versus Q²/Mmore »« less
