THEORETICAL ASPECTS OF THE PION-PION INTERACTION [PDF]
International Journal of Modern Physics A, 2006 We give a brief review of the theoretical description of low energy pion-pion scattering by the combined use of Chiral Perturbation Theory and Roy equations, an update of the Regge parametrization of ππ cross sections at high energies, and a short discussion of the scalar radius of the pion.

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.

Progress of Theoretical Physics, 1962 The modified effective range formulas for S- and P-wave pion-pion scattering which contain the effect of nucleon closed loops are derived using the chain approximation. These are extensions along the lines of Chew and Mandelstam, and Okubo and Miyamoto.

Dispersive analysis of pion-nucleon scattering and the pion-nucleon sigma term [PDF]
, 2018 Pion--nucleon scattering is one of the most fundamental processes in nuclear and hadronic physics, with applications that range from the scalar couplings of the nucleon to the long-range part of two-pion-exchange potentials and three-nucleon forces in ...

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.

Finkelstein-Rubinstein constraints for the Skyrme model with pion masses [PDF]
, 2006 The Skyrme model is a classical field theory modelling the strong interaction between atomic nuclei. It has to be quantized in order to compare it to nuclear physics.

Pion damping width and pion spectral function in hot pion gas [PDF]
, 2022 The temperature behaviour of the pion width in the hadronic phase is investigated in the framework of the NJL model. The contribution to the width from the pion-pion collision is considered with a scalar sigma-meson as an intermediate state.

Pion Production in Pion Nucleon Scattering and Pion-Pion Interaction [PDF]
Progress of Theoretical Physics, 1962 The reaction pi + N yields 2 pi + N is discussed. The production process is assumed to take place mainly via pi - pi interactions, which are studied using an extrapolation formula (G. F. Chew and F. E. Low, Phys. Rev., 113: 1640 (1959)). A program giving a consistent explanation to the process at 0.3 to 1.5 Bev is presented.

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.

4-momentum conservation as the principal framework for mesonic decay: The case of helium-5-lambda [PDF]
AIP AdvancesNegative-pion and neutral-pion mesonic decays of the hypernucleus HeΛ5 are investigated within two-body and three-body relativistic kinematics in the rest frame of the hypernucleus. 4-momentum conservation fully constrains the two-body decay, giving rise
