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

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 ...

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.

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 ...

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

Pion PDFs confronted by fixed-target charmonium production
AAPPS Bulletin, 2023 The pion, as the Goldstone boson of the strong interaction, is the lightest QCD bound state and responsible for the long-range nucleon-nucleon interaction inside the nucleus.

Dispersion relations for hadronic light-by-light and the muon g − 2 [PDF]
EPJ Web of Conferences, 2020 The largest uncertainties in the Standard Model calculation of the anomalous magnetic moment of the muon (g−2)µ come from hadronic effects, namely hadronic vacuum polarization (HVP) and hadronic lightby-light (HLbL) contributions.

Perioperative posterior ischemic optic neuropathy (PION) after open aortic surgery
Annals of Vascular Surgery - Brief Reports and Innovations, 2022 Perioperative posterior ischemic optic neuropathy (PION) is a rare but potentially devastating condition. A correlation of PION with major surgical procedures has been established, particularly in cases of spine and cardiovascular surgery.

Physical Review Letters, 1959 In order to study the direct interaction of the incident pion with a virtual pion in the meson cloud surrounding a nucleon, the reaction pi + p yields pi /sup +/ + pi /sup -/ + n was investigated in the energy range from 260 to 430 Mev. Negative pion beams impinged on a 4-in.thick liquid hydrogen target.

Physical Review, 1960 A liquid hydrogen target was bombarded by negative pions of energies 260. 317, 371, and 427 Mev. Positive pions from the reaction pi /sup -/ + p yields pi /sup +/ + pi /sup -/ + n were dete cted by the use of a counter telescope, that selected the pi /sup +/ by its characteristic pi - mu decay.
