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-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

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. (

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 ...

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 ...

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.

Crystals, 2017 Evolution in time of radiation defects induced by negatively-charged pions and muons in crystals with diamond structures is considered. Negative pions and muons are captured by the nucleus and ionize an appropriate host atom, forming a positively-charged

Regge analysis of pion-pion (and pion-kaon) scattering for energy s^{1/2}>1.4 GeV [PDF]
, 2003 We perform a detailed Regge analysis of NN, pion-N and pion-pion scattering. From it, we find expressions that represent the pion-pion scattering amplitudes with an accuracy of a few percent, for exchange of isospin zero, and $\sim15%$ for exchange of ...
