Valence-quark distribution of the kaon and pion from lattice QCD

open access: yes, 2021
We present the first lattice-QCD calculation of the kaon valence-quark distribution functions using the large-momentum effective theory (LaMET) approach.

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.

Contact interaction analysis of pion GTMDs [PDF]

open access: yes, 2020
A contact interaction is used to calculate an array of pion twist-two, -three and -four generalised transverse light-front momentum dependent parton distribution functions (GTMDs).

On the Usefulness of Two Small-Scale In Vitro Setups in the Evaluation of Luminal Precipitation of Lipophilic Weak Bases in Early Formulation Development

open access: yesPharmaceutics, 2020
A small-scale biphasic dissolution setup and a small-scale dissolution-permeation (D-P) setup were evaluated for their usefulness in simulating the luminal precipitation of three lipophilic weak bases—dipyridamole, ketoconazole and itraconazole ...

Symmetry, symmetry breaking, and pion parton distributions [PDF]

open access: yesPhysical Review D, 2019
Pion valence, glue and sea distributions are calculated using a continuum approach to the two valence-body bound-state problem. Since the framework is symmetry preserving, physical features of the distributions are properly expressed.

Chiral symmetry breaking: Current experimental status and prospects [PDF]

open access: yesEPJ Web of Conferences, 2023
Chiral symmetry, linked to the smallness of the quark masses compared to the QCD bound states, and its breaking pattern are exploited in effective field theory to describe a multitude of phenomena by a few low-energy constants.

First Monte Carlo Global QCD Analysis of Pion Parton Distributions. [PDF]

open access: yesPhysical Review Letters, 2018
We perform the first global QCD analysis of parton distribution functions (PDFs) in the pion, combining πA Drell-Yan data with leading neutron electroproduction from HERA within a Monte Carlo approach based on nested sampling.

Evolution in Time of Radiation Defects Induced by Negative Pions and Muons in Crystals with a Diamond Structure

open access: yesCrystals, 2017
Evolution in time of radiation defects induced by negatively-charged pions and muons in crystals with diamond structures is considered. Negative pions and muons are captured by the nucleus and ionize an appropriate host atom, forming a positively-charged

Pion PDFs confronted by fixed-target charmonium production

open access: yesAAPPS Bulletin, 2023
The pion, as the Goldstone boson of the strong interaction, is the lightest QCD bound state and responsible for the long-range nucleon-nucleon interaction inside the nucleus.

Dispersion relations for hadronic light-by-light and the muon g − 2 [PDF]

open access: yesEPJ Web of Conferences, 2020
The largest uncertainties in the Standard Model calculation of the anomalous magnetic moment of the muon (g−2)µ come from hadronic effects, namely hadronic vacuum polarization (HVP) and hadronic lightby-light (HLbL) contributions.
