Theoretical progress in describing the B-meson lifetimes [PDF]

, 2001
The present status of the theoretical estimates of the difference between the widths of the neutral Bs-mesons and of the B-meson lifetime ratios is reviewed. In particular, the lattice results for the matrix elements of the relevant (delta B=2)-operators

The QCD equation of state at finite density from analytical continuation [PDF]

, 2016
We determine the equation of state of QCD at finite chemical potential, to order $(\mu_B/T)^6$, for a system of 2+1 quark flavors. The simulations are performed at the physical mass for the light and strange quarks on several lattice spacings; the ...

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.

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 ...

SU(N) gauge theories in the presence of a topological term [PDF]

, 2007
We review recent results on the theta dependence of the ground-state energy and spectrum of four-dimensional SU(N) gauge theories, where theta is the coefficient of the CP-violating topological term F-Fdual in the Lagrangian.

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.

$B\to Kl^+l^-$ decay form factors from three-flavor lattice QCD [PDF]

, 2016
We compute the form factors for the $B \to Kl^+l^-$ semileptonic decay process in lattice QCD using gauge-field ensembles with 2+1 flavors of sea quark, generated by the MILC Collaboration.

Jet quenching in a strongly interacting plasma - A lattice approach [PDF]

, 2013
The phenomenon of jet quenching, related to the momentum broadening of a high-energy parton, provides important experimental evidence for the production of a strongly coupled, deconfined medium in heavy-ion collisions.
