Low-Momentum-Transfer Pion-Pion Scattering [PDF]

open access: yesPhysical Review, 1963
High-energy effects at low momentum transfer, both in the direct and in the crossed channel, are introduced into a self-consistent calculation of low- energy pi - pi scattering. These effects are assumed to be dominated by top- level please delete the above abstract no. 39923=====

Charge dependence of the pion-nucleon coupling constant

open access: yesЯдерна фізика та енергетика, 2015
On the basis of the Yukawa potential we study the pion-nucleon coupling constants for the neutral and charged pions assuming that nuclear forces at low energies are mainly determined by the exchange of virtual pions.

High temperature Bose-Einstein condensation

open access: yesEPJ Web of Conferences, 2016
The indications of a possible pion condensation at the LHC are summarized. The condensation is predicted by the non-equilibrium hadronization model for 2.76 TeV Pb+Pb collisions at the LHC.

Studying ρ–N couplings with HADES in pion-induced reactions

open access: yesEPJ Web of Conferences, 2016
The High-Acceptance Di-Electron Spectrometer (HADES) operates at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt with pion, proton and heavyion beams provided by the synchrotron SIS18.

Pion Loop Contribution to the Electromagnetic Pion Charge Radius

open access: yes, 1993
A phenomenological Dyson-Schwinger equation approach to QCD, formalised in terms of a QCD based model field theory, is used to calculate the electromagnetic charge radius of the pion.

Aspects of Meson Condensation

open access: yesEPJ Web of Conferences, 2016
In this work pion and kaon condensation in the framework of chiral perturbation theory is studied. I consider a system at vanishing temperature with nonzero isospin chemical potential and strangeness chemical potential; meson masses and mixing in the ...

Azimuthal spin asymmetries in pion-polarized proton induced Drell–Yan process at COMPASS using holographic light-front QCD

open access: yesEuropean Physical Journal C: Particles and Fields
We compute all the leading-twist azimuthal spin asymmetries in the pion-proton induced Drell–Yan process. These spin asymmetries arise from convolutions of the leading-twist transverse-momentum-dependent parton distributions (TMDs) of both the incoming ...
