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 ...

$B\to Kl^+l^-$ 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.

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 ...

Towards precision heavy flavour physics from lattice QCD [PDF]

, 2010
I convey an idea of the significant recent progress, which opens up good perspectives for high-precision ab-initio computations in heavy flavour physics based on lattice QCD.

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.

Results and Perspectives in HEP, vis-a-vis Lattice QCD [PDF]

, 1999
I review in this presentation some aspects of phenomenology in High Energy Physics which are related to recent and possibly future progress in lattice QCD.

Hadrons and Nuclei

, 2019
This document is one of a series of whitepapers from the USQCD collaboration. Here, we discuss opportunities for lattice QCD calculations related to the structure and spectroscopy of hadrons and nuclei.

Most Strange Dibaryon from Lattice QCD [PDF]

, 2018
The $\Omega\Omega$ system in the $^1S_0$ channel (the most strange dibaryon) is studied on the basis of the (2+1)-flavor lattice QCD simulations with a large volume (8.1 fm)$^3$ and nearly physical pion mass $m_{\pi}\simeq 146$ MeV at a lattice spacing ...
