Chiral extrapolation of the sigma resonance
Physics Letters B, 2018 We analyze results on isoscalar ππ scattering from a Nf=2+1 lattice QCD calculation by the HadronSpectrum collaboration by re-summing the two-flavor chiral scattering amplitude of the next-to-leading order in the so-called inverse amplitude method.

Hard exclusive pion electroproduction at backward angles with CLAS
Physics Letters B, 2018 We report on the first measurement of cross sections for exclusive deeply virtual pion electroproduction off the proton, ep→e′nπ+, above the resonance region at backward pion center-of-mass angles.

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.

Connected and disconnected contractions in pion–pion scattering
Nuclear Physics B, 2017 We show that the interplay of chiral effective field theory and lattice QCD can be used in the evaluation of so-called disconnected diagrams, which appear in the study of the isoscalar and isovector channels of pion-pion scattering and have long been a major challenge for the lattice community. By means of partially-quenched chiral perturbation theory,

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.

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

European Physical Journal C: Particles and FieldsWe 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 ...

Post-selected flavor entanglement in pion–pion scattering
European Physical Journal C: Particles and FieldsQuantum entanglement provides a quantitative measure of nonclassical correlations and plays a central role in quantum information theory. Identifying and quantifying the mechanisms by which fundamental interactions generate or suppress entanglement is ...

Gluon distribution and mass decomposition of the pion and kaon
European Physical Journal C: Particles and FieldsWe present the gluon distribution functions of the pion and kaon in small-x and large-x regions, and compare them with the results obtained from lattice QCD and continuum Schwinger function methods.
