Thermal conductivity of hot pionic medium due to pion self-energy for $\pi\sigma$ and $\pi\rho$ loops

, 2015
The thermal conductivity of pionic medium has been evaluated with the help of its standard expression from the relaxation time approximation, where inverse of pion relaxation time or pion thermal width has been obtained from the imaginary part of pion ...

Hard pion bremsstrahlung in the Coulomb region

, 2007
Hard high-energy pion-nucleus bremsstrahlung, $\pi^- +A\to\pi^- +\gamma +A$, is studied in the Coulomb region, i.e. the small-angle region where the nuclear scattering is dominated by the Coulomb interaction.

Observation and investigation of πK atoms

EPJ Web of Conferences, 2017
There is accurate relation between lifetime of atoms, consisting of pion and kaon, and a difference of S-wave pion kaon scattering length with isospin 1/2 and 3/2: |a1/2 - a3/2 |. This difference is predicted by low energy QCD.

Soft pion theorem for hard near threshold pion production

, 2001
We prove new soft pion theorem for the near threshold pion production by a hard electromagnetic probe. This theorem relates various near threshold pion production amplitudes to the nucleon distribution amplitudes.

The Effect of the Pion-Pion Interaction on the Pion-Nucleon Scattering [PDF]

Progress of Theoretical Physics, 1961
It is suggested that the low-energy pion-nucleon p-wave shifts will be well understood by taking account of the effects of not only the pion-pion P-wave interaction but also the pion-pion S-wave interaction into the equations for the p-wave scattering amplitudes derived by Chew, Goldberger, Low, and Nambu.

Pion Loop Contribution to the Electromagnetic Pion Charge Radius

, 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.

Electromagnetic Structure of the Pion

, 2013
In this work, we analyze the electromagnetic structure of the pion. We calculate its electromagnetic radius and electromagnetic form factor in low and intermediate momentum range. Such observables are determined by means of a theoretical model that takes

Charge dependence of the pion-nucleon coupling constant

Ядерна 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.
