Aspects of chiral transition in a Hadron Resonance Gas model [PDF]

open access: yesEPJ Web of Conferences, 2022
We study the chiral condensate for 2 + 1 flavor QCD with physical quarks within a non-interacting Hadron Resonance Gas (HRG) model. By including the latest information on the mass variation of the hadrons concerning the light quark mass, from lattice QCD

ΛΛ and NΞ interactions from lattice QCD near the physical point [PDF]

open access: yesNuclear Physics, 2019
The $S$-wave $\Lambda\Lambda$ and $N \Xi$ interactions are studied on the basis of the (2+1)-flavor lattice QCD simulations close to the physical point ($m_\pi \simeq 146{\rm{MeV}}$ and $m_K \simeq 525{\rm{MeV}}$).

Lattice QCD and Three-Particle Decays of Resonances [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 2019
Most strong-interaction resonances have decay channels involving three or more particles, including many of the recently discovered X, Y, and Z resonances.

Pion valence quark distribution from matrix element calculated in lattice QCD [PDF]

open access: yesPhysical Review D, 2019
We present the first exploratory lattice QCD calculation of the pion valence quark distribution extracted from spatially separated current-current correlations in coordinate space.

Nuclear matrix elements from lattice QCD for electroweak and beyond-Standard-Model processes [PDF]

open access: yes, 2020
Over the last decade, numerical solutions of Quantum Chromodynamics (QCD) using the technique of lattice QCD have developed to a point where they are beginning to connect fundamental aspects of nuclear physics to the underlying degrees of freedom of the ...

Low-energy constants in the chiral Lagrangian with baryon octet and decuplet fields from Lattice QCD data on CLS ensembles

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We perform an analysis of Lattice QCD data on baryon octet and decuplet masses based on the chiral SU(3) Lagrangian. Low-energy constants (LEC) are adjusted to describe baryon masses from a large set of CLS ensembles, where finite-box and discretization ...

An Introduction to Finite Temperature Quantum Chromodynamics on the Lattice [PDF]

open access: yes, 1998
In these lectures, we introduce finite temperature QCD on the lattice to non-experts of the subject. We first formulate lattice QCD both at zero and finite temperatures.

Light-meson leptonic decay rates in lattice QCD+QED [PDF]

open access: yesPhysical Review D, 2019
The leading electromagnetic (e.m.) and strong isospin-breaking corrections to the $\pi^+ \to \mu^+ \nu[\gamma]$ and $K^+ \to \mu^+ \nu[\gamma]$ leptonic decay rates are evaluated for the first time on the lattice.

Dispersive determination of the HVP contribution to the muon g − 2 [PDF]

open access: yesEPJ Web of Conferences, 2023
The determination of hadronic vacuum polarization (HVP) from e+e− → hadrons cross-section data, in the energy region relevant for the anomalous magnetic moment of the muon, has recently been challenged by lattice-QCD calculations, especially for the ...

Searching for the QCD critical point through constant entropy density contours [PDF]

open access: yesEPJ Web of Conferences
We propose a novel method to locate the QCD critical point by constructing an expansion along contours of constant entropy density. Applying two independent analyses of lattice QCD data at zero baryon chemical potential, we find a critical point at Tc ...
