The x-dependence of hadronic parton distributions: A review on the progress of lattice QCD. [PDF]

Eur Phys J A Hadron Nucl, 2021
In this article, we review recent lattice calculations on the x-dependence of parton distributions, with the latter providing information on hadron structure.

Excited bottomonia in quark-gluon plasma from lattice QCD [PDF]

Physics Letters B, 2020
We present the first lattice QCD study of up to 3S and 2P bottomonia at non-zero temperatures. Correlation functions of bottomonia were computed using novel bottomonium operators and a variational technique, within the lattice non-relativistic QCD ...

Update on ɛK with lattice QCD inputs

EPJ Web of Conferences, 2018
We report updated results for ɛK, the indirect CP violation parameter in neutral kaons, which is evaluated directly from the standard model with lattice QCD inputs. We use lattice QCD inputs to fix B⌢K,Vcb,ξ0,ξ2,Vus, and mc(mc).

NΩ dibaryon from lattice QCD near the physical point [PDF]

Physics Letters B, 2019
The nucleon(N)-Omega(Ω) system in the S-wave and spin-2 channel (S25) is studied from the (2+1)-flavor lattice QCD with nearly physical quark masses (mπ≃146MeV and mK≃525MeV).

Lattice QCD and Baryon-Baryon Interactions: HAL QCD Method [PDF]

Frontiers in Physics, 2020
In this article, we review the HAL QCD method to investigate baryon-baryon interactions, such as nuclear forces in lattice QCD. We first explain our strategy in detail to investigate baryon-baryon interactions by defining potentials in field theories ...

Scattering processes and resonances from lattice QCD [PDF]

, 2017
The vast majority of hadrons observed in nature are not stable under the strong interaction, rather they are resonances whose existence is deduced from enhancements in the energy dependence of scattering amplitudes.

Lattice QCD Application Development within the US DOE Exascale Computing Project [PDF]

EPJ Web of Conferences, 2018
In October, 2016, the US Department of Energy launched the Exascale Computing Project, which aims to deploy exascale computing resources for science and engineering in the early 2020’s.

Design and performance of GaSb-based quantum cascade detectors. [PDF]

Nanophotonics
Abstract InAs/AlSb quantum cascade detectors (QCDs) grown strain‐balanced on GaSb substrates are presented. This material system offers intrinsic performance‐improving properties, like a low effective electron mass of the well material of 0.026 m0, enhancing the optical transition strength, and a high conduction band offset of 2.28 eV, reducing the ...

Gravitational Form Factors of the Proton from Lattice QCD. [PDF]

Physical Review Letters, 2023
The gravitational form factors (GFFs) of a hadron encode fundamental aspects of its structure, including its shape and size as defined from, e.g., its energy density.

Quantum simulation of lattice QCD with improved Hamiltonians [PDF]

Physical Review D, 2023
Quantum simulations of lattice gauge theories are anticipated to directly probe the real time dynamics of QCD, but scale unfavorably with the required truncation of the gauge fields.
