Zeszyty Wiejskie, 2023 In the press of the interwar period, among the group of Warsaw opinion-forming periodicals, the three largest literary and social weeklies dominated – the liberal Wiadomości Literackie, the pro-Sanacja Pion and the right-wing Prosto z Mostu.

Lattice calculation of the pion transition form factor with Nf=2+1 Wilson quarks [PDF]
Physical Review D, 2019 We present a lattice QCD calculation of the double-virtual neutral pion transition form factor, with the goal to cover the kinematic range relevant to hadronic light-by-light scattering in the muon $g-2$.

Two-pion contribution to hadronic vacuum polarization [PDF]
Journal of High Energy Physics, 2018 A bstractWe present a detailed analysis of e+e− → π+π− data up to s=1$$ \sqrt{s}=1 $$ GeV in the framework of dispersion relations. Starting from a family of ππ P-wave phase shifts, as derived from a previous Roy-equation analysis of ππ scattering, we ...

Generalizing the relativistic quantization condition to include all three-pion isospin channels [PDF]
Journal of High Energy Physics, 2020 We present a generalization of the relativistic, finite-volume, three-particle quantization condition for non-identical pions in isosymmetric QCD. The resulting formalism allows one to use discrete finite-volume energies, determined using lattice QCD, to

Gluon parton distribution of the pion from lattice QCD
Physics Letters B, 2021 We present the first determination of the x-dependent pion gluon distribution from lattice QCD using the pseudo-PDF approach. We use lattice ensembles with 2+1+1 flavors of highly improved staggered quarks (HISQ), generated by MILC Collaboration, at two ...

Three-pion contribution to hadronic vacuum polarization [PDF]
Journal of High Energy Physics, 2019 We address the contribution of the 3π channel to hadronic vacuum polarization (HVP) using a dispersive representation of the e+e− → 3π amplitude. This channel gives the second-largest individual contribution to the total HVP integral in the anomalous ...

Pion and kaon structure at the electron-ion collider [PDF]
European Physical Journal A, 2019 .Understanding the origin and dynamics of hadron structure and in turn that of atomic nuclei is a central goal of nuclear physics. This challenge entails the questions of how does the roughly 1GeV mass-scale that characterizes atomic nuclei appear; why ...

Valence parton distribution of the pion from lattice QCD: Approaching the continuum limit [PDF]
, 2020 We present a high-statistics lattice QCD determination of the valence parton distribution function (PDF) of pion, with a mass of $300$ MeV, using two very fine lattice spacings of $a=0.06$ fm and $0.04$ fm.

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 ...
