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 (

PION–PION SCATTERING ABOVE RESONANCES [PDF]
Meson 2002, 2003 We model large angle intermediate energy pion-pion scattering by the pQCD two-gluon (2g) exchange contribution and discuss the onset of the dominance of the Glauber-Gribov-Landshoff (GGL) component. The pQCD 2g exchange contribution becomes substantial already at $|t|\sim$ 1 GeV^{2}, but the pQCD exchange dominance is deferred to $|t|\sim$ 3 GeV^{2 ...

Effect of bicarbonate buffer on artificial membrane permeation of drugs [PDF]
ADMET and DMPKBackground and purpose: The pH value of the small intestine is physiologically maintained by bicarbonate buffer (BCB). However, the effect of BCB on the membrane permeation of drugs has not been investigated. The purpose of this study was to investigate

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

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 ...

Pion-Pion Interaction and Pion-Nucleon Scattering [PDF]
Progress of Theoretical Physics, 1960 Pion-pion interaction is analyzed by using the dispersion relation for pion-nucleon scattering obtained by keeping the momentum transfer between an initial pion and a final nucleon constant. In order to take into account the singularity of two-pion threshold in the dispersion relation, the dispersion relation may be regarded as an integral equation for

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 -/)
