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

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

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

Phases of cold holographic QCD: Baryons, pions and rho mesons
SciPost Physics, 2023 We improve the holographic description of isospin-asymmetric baryonic matter within the Witten-Sakai-Sugimoto model by accounting for a realistic pion mass, computing the pion condensate dynamically, and including rho meson condensation by allowing the ...

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

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

Pharmaceutics, 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 ...

Pion damping width and pion spectral function in hot pion gas [PDF]
, 2022 The temperature behaviour of the pion width in the hadronic phase is investigated in the framework of the NJL model. The contribution to the width from the pion-pion collision is considered with a scalar sigma-meson as an intermediate state. It is shown that the pion width significantly broadens at $T>0.1$ GeV.

Pion valence structure from Ioffe-time parton pseudodistribution functions [PDF]
Physical Review D, 2019 We present a calculation of the pion valence quark distribution extracted using the formalism of reduced Ioffe-time pseudodistributions or more commonly known as pseudo-PDFs.

Pion PDFs confronted by fixed-target charmonium production
AAPPS 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.
