Thermodynamics of the QCD plasma and the large-N limit [PDF]

, 2009
The equilibrium thermodynamic properties of the SU(N) plasma at finite temperature are studied non-perturbatively in the large-N limit, via lattice simulations.

Quantum chromodynamics with advanced computing [PDF]

, 2008
We survey results in lattice quantum chromodynamics from groups in the USQCD Collaboration. The main focus is on physics, but many aspects of the discussion are aimed at an audience of computational physicists.Comment: 17 pp.

$B\to\pi\ell\ell$ form factors for new-physics searches from lattice QCD [PDF]

, 2015
The rare decay $B\to\pi\ell^+\ell^-$ arises from $b\to d$ flavor-changing neutral currents and could be sensitive to physics beyond the Standard Model.

Computation of the strong coupling in QCD with two dynamical flavours [PDF]

, 2004
We present a non-perturbative computation of the running of the coupling alpha_s in QCD with two flavours of dynamical fermions in the Schroedinger functional scheme. We improve our previous results by a reliable continuum extrapolation.

Momentum broadening of partons on the light cone from the lattice [PDF]

, 2013
The jet quenching parameter describes the momentum broadening of a high-energy parton moving through the quark-gluon plasma. Following an approach originally proposed by Caron-Huot, we discuss how one can extract information on the collision kernel ...

Equation of state in 2+1 flavor QCD with improved Wilson quarks by the fixed scale approach [PDF]

, 2012
We study the equation of state in 2+1 flavor QCD with nonperturbatively improved Wilson quarks coupled with the RG-improved Iwasaki glue. We apply the $T$-integration method to nonperturbatively calculate the equation of state by the fixed-scale approach.

Non-perturbative quark mass renormalisation and running in $N_f=3$ QCD [PDF]

, 2018
We determine from first principles the quark mass anomalous dimension in Nf=3 QCD between the electroweak and hadronic scales. This allows for a fully non-perturbative connection of the perturbative and non-perturbative regimes of the Standard Model in ...

The Role of Lattice QCD in Searches for Violations of Fundamental Symmetries and Signals for New Physics

, 2019
This document is one of a series of whitepapers from the USQCD collaboration. Here, we discuss opportunities for Lattice Quantum Chromodynamics (LQCD) in the research frontier in fundamental symmetries and signals for new physics.
