Determination of the pion-nucleon coupling constant and scattering lengths [PDF]
, 2000 We critically evaluate the isovector GMO sum rule for forward pion-nucleon scattering using the recent precision measurements of negatively charged pion-proton and pion-deuteron scattering lengths from pionic atoms.

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

Neutrino-induced coherent pion production off nuclei reexamined
, 2009 It is pointed out that so far all theoretical estimates of coherent pion production off nuclei induced by neutrinos rely on the 'local approximation' well known in photonuclear physics. The effects of dropping this approximation are discussed.

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 ...

The width of the Δ-resonance at two loop order in baryon chiral perturbation theory
Physics Letters B, 2016 We calculate the width of the delta resonance at leading two-loop order in baryon chiral perturbation theory. This gives a correlation between the leading pion–nucleon–delta and pion–delta couplings, which is relevant for the analysis of pion–nucleon ...

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.
