Dispersion relation for hadronic light-by-light scattering: two-pion contributions [PDF]
Journal of High Energy Physics, 2017 In this third paper of a series dedicated to a dispersive treatment of the hadronic light-by-light (HLbL) tensor, we derive a partial-wave formulation for two-pion intermediate states in the HLbL contribution to the anomalous magnetic moment of the muon (

Dispersion relation for hadronic light-by-light scattering: pion pole [PDF]
Journal of High Energy Physics, 2018 The pion-pole contribution to hadronic light-by-light scattering in the anomalous magnetic moment of the muon (g − 2)μ is fully determined by the doubly-virtual pion transition form factor.

Study of Pion-Pion Interactions From Pion Production by Pions [PDF]
Physical Review Letters, 1962 Reactions pi /sup plus or minus / + p yields pi /sup plus or minus / + pi /sup +/ + n were studied at a n incident pion momentum of 1.75 Bev/c. The experimental apparatus and procedure are described in detail, and the measured and calculated data are presented and discussed. Evidence was found of a pion-pion interaction in the ( pi /sup +/- pi /sup -/)

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 ...

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.

Pion-Pion Interaction and Pion Production in Pion-Nucleon Collision [PDF]
Progress of Theoretical Physics, 1960 The evidence for the n;-n; interaction is investigated by considering the angular distribution of nucleon in pion production by pion-nucleon collision. It is shown that it will be quite difficult to understand the sharp forward angular distribution of nucleon without considering n;-n; interaction.

Detection of the Characteristic Pion-Decay Signature in Supernova Remnants [PDF]
Science, 2013 Accelerated Protons Although cosmic rays were first detected a hundred years ago, their origin is still not fully understood. Comic rays are high-energy particles, mostly protons, which bombard Earth from outer space.

Valence parton distribution function of pion from fine lattice [PDF]
Physical Review D, 2019 We present a lattice QCD study of valence parton distribution inside the pion within the framework of Large Momentum Effective Theory. We use a mixed action approach with 1-HYP smeared valence Wilson clover quarks on 2+1 flavor HISQ sea with the valence ...

Emergence of pion parton distributions [PDF]
Physical Review D, 2022 Supposing only that there is an effective charge which defines an evolution scheme for parton distribution functions (DFs) that is all-orders exact, strict lower and upper bounds on all Mellin moments of the valence-quark DFs of pion-like systems are ...
