Title: Color screening in ( $2 + 1$ )-flavor QCD

Abstract

Here, we study correlation functions of spatially separated static quark-antiquark pairs in (2+1)-flavor QCD in order to investigate onset and nature of color screening at high temperatures. We perform lattice calculations in a wide temperature range, 140 ≤ T ≤ 5814 MeV, using the highly improved staggered quark action and several lattice spacings to control discretization effects. By comparing at high temperatures our lattice results to weak-coupling calculations, as well as to the zero temperature result for the energy of a static quark-antiquark pair, we observe that color screening sets in at rT ≈ 0.3. Furthermore, we also observe that in the range 0.3 ≲ rT ≲ 0.6 weak-coupling calculations in the framework of suitable effective field theories provide an adequate picture of color screening.

Meson screening masses in ( $2 + 1$ )-flavor QCD

Journal Article Bazavov, A. ; Dentinger, S. ; Ding, H. -T. ; ... - Physical Review D

We present lattice QCD results for mesonic screening masses in the temperature range 140 MeV ≲ T ≲ 2500 MeV. Our calculations were carried out using (2+1) flavors of the Highly Improved Staggered Quark (HISQ) action, with a physical value for the strange quark mass and two values of the light quark mass corresponding to pion masses of 160 MeV and 140 MeV. Continuum extrapolated results were obtained using calculations with a variety of lattice spacings corresponding to temporal lattice extents N_τ = 6 16. We discuss the implications of these results for the e effective restoration of various symmetriesmore »« less

Equation of state in $2 + 1$ flavor QCD at high temperatures

Journal Article Bazavov, A. ; Petreczky, P. ; Weber, J. H. - Physical Review D

We calculate the Equation of State at high temperatures in 2+1 flavor QCD using the highly improved staggered quark (HISQ) action. We study the lattice spacing dependence of the pressure at high temperatures using lattices with temporal extent N(tau) = 6, 8, 10 and 12 and perform continuum extrapolations. We also give a continuum estimate for the Equation of State up to temperatures T = 2 GeV, which are then compared with results of the weak-coupling calculations. We find a reasonably good agreement with the weak-coupling calculations at the highest temperatures.

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. The lattice-QCD calculations were done using nine ensembles of gauge configurations generated by the MILC Collaborationmore »« less

Strong coupling constant and heavy quark masses in ( $2 + 1$ )-flavor QCD

Journal Article Petreczky, P. ; Weber, J. H. - Physical Review D

We present a determination of the strong coupling constant and heavy quark masses in (2+1)-flavor QCD using lattice calculations of the moments of the pseudo-scalar quarkonium correlators at several values of the heavy valence quark mass with Highly Improved Staggered Quark (HISQ) action. We determine the strong coupling constant in themore »« less

$B$ -meson decay constants from $2 + 1$ -flavor lattice QCD with domain-wall light quarks and relativistic heavy quarks

Journal Article Christ, Norman H. ; Flynn, Jonathan M. ; Izubuchi, Taku ; ... - Physical Review. D, Particles, Fields, Gravitation and Cosmology

We calculate the B-meson decay constants f_B, f_{B_s}, and their ratio in unquenched lattice QCD using domain-wall light quarks and relativistic b quarks. We use gauge-field ensembles generated by the RBC and UKQCD collaborations using the domain-wall fermion action and Iwasaki gauge action with three flavors of light dynamical quarks. We analyze data at two lattice spacings of a ≈ 0.11, 0.086 fm with unitary pion masses as light as M_π ≈ 290 MeV; this enables us to control the extrapolation to the physical light-quark masses and continuum. For the b quarks we use the anisotropic clover action with themore »« less
