Transverse pion structure beyond leading twist in constituent models [PDF]
, 2016 The understanding of the pion structure as described in terms of transverse-momentum dependent parton distribution functions (TMDs) is of importance for the interpretation of currently ongoing Drell-Yan experiments with pion beams.

Dynamical spin effects in the pion [PDF]
, 2017 We take into account dynamical spin effects in the holographic light-front pion wavefunction in order to predict the pion radius, decay constant, the pion electromagnetic and photon-to-pion transition form factors. We report a striking improvement in the

Dispersion relation for hadronic light-by-light scattering: two-pion contributions
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 (

Nonperturbative partonic quasidistributions of the pion from chiral quark models
Physics Letters B, 2017 We evaluate nonperturbatively the quark quasidistribution amplitude and the valence quark quasidistribution function of the pion in the framework of chiral quark models, namely the Nambu–Jona-Lasinio model and the Spectral Quark Model.

Pion Detection Using Single Photon Avalanche Diodes
Sensors, 2023 We present the first reported use of a CMOS-compatible single photon avalanche diode (SPAD) array for the detection of high-energy charged particles, specifically pions, using the Super Proton Synchrotron at CERN, the European Organization for Nuclear ...

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 ...

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 Production by Negative Pions [PDF]
Physical Review Letters, 1961 The reaction pi /sup -/ + p yields pi /sup +/ + pi /sup -/ + n is studied for incident T/sub i- = 365 and 432 Mev. The energy spectra of the ernergent pi /sup +/ mesons are measured at various angles with respect to the incident pi /sup -/ beam. The differential cross sections are analyzed in terms of pion-pion interactions and pionnuclecn resonances. (
