Pion nucleus Drell–Yan process and parton transverse momentum in the pion
European Physical Journal C: Particles and Fields, 2018 We present a thorough analysis of unpolarized Drell–Yan (DY) pair production in pion–nucleus scattering. On the nucleus side, we use nuclear parton distributions along with parametrisations of the nucleon partonic transverse distribution available in the

The European Physical Journal A, 2020 Both gravitons and pions are described by non-linear and non-renormalizable actions at low energies. These are most usefully treated by effective field theory, which is a full quantum field theoretic approach that relies only on the low energy degrees of freedom and their interactions.

Coherent Pion Production in Neutrino Nucleus Scattering
, 2016 In this article, we study the coherent pion production in neutrino-nucleus interaction in the resonance region using the formalism based on partially conserved axial current (PCAC) theorem which relates the neutrino-nucleus cross section to the pion ...

Pion-Nucleon Scattering and Pion-Pion Interaction [PDF]
Progress of Theoretical Physics, 1962 Applying Cini-Fubini approximation to the Mandelstam representation for pion-nucleon scattering amplitude, we treat explicitly the effect of pion-pion interaction to be added to the dispersion relation given by Chew, Goldberger, Low and Nambu. On account of scanty information on the contribution to tl:e dispersion .integral from high-mass states, we ...

I=2 pion scattering length with the parametrized fixed point action
, 2003 We report on the pion-pion scattering length in the I=2 channel using the parametrized fixed point action. Pion masses of 320 MeV were reached in this quenched calculation of the scattering length.Comment: 3 pages, 5 figures, Lattice2003 ...

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.

Pion Form Factor in Chiral Limit of Hard-Wall AdS/QCD Model
, 2007 We develop a formalism to calculate form factor and charge density distribution of pion in the chiral limit using the holographic dual model of QCD with hard-wall cutoff. We introduce two conjugate pion wave functions and present analytic expressions for

Nonequilibrium Pion Distribution within the Zubarev Approach
Particles, 2020 We discuss how the non-equilibrium process of pion production within the Zubarev approach of the non-equilibrium statistical operator leads to a theoretical foundation for the appearance of a non-equilibrium pion chemical potential for the pion ...

Evaluation of the two lightest quark masses
Ядерна фізика та енергетика, 2017 Simple relations between the masses of the two lightest up and down quarks were obtained on the basis of the simple physically based model compatible with the present-day theory of strong interactions, i.e. with quantum chromodynamics.

Ядерна фізика та енергетика, 2017 Charge dependence of the pion-nucleon coupling constants and the 1S0-state low-energy nucleon-nucleon scattering parameters are studied on the basis of the Yukawa meson theory.
