recommendations! Published in 2025 at "Journal of High Energy Physics"

DOI: 10.1007/jhep06(2025)229

Abstract: We study the electromagnetic and meson-photon transition form factors (TFF) of light pseudoscalar mesons from the perturbative QCD (pQCD) approach. To comprehensively account for both the longitudinal and transverse nonperturbative dynamics of hadronic constituents, we… read more here.

recommendations! Published in 2024 at "Chinese Physics Letters"

DOI: 10.1088/0256-307x/42/2/020201

Abstract: Several aspects of the internal structure of pseudoscalar mesons, accessible through generalized parton distributions in their zero-skewness limit, are examined. These include electromagnetic and gravitational form factors related to charge and mass densities; and distributions… read more here.

DOI: 10.1103/physrevd.101.115041

Abstract: We analyze contributions to the electric dipole (EDM) and Schiff (SFM) moments of deuteron induced by the CP-violating three-pseudoscalar meson couplings using phenomenological Lagrangian approach involving nucleons and pseudoscalar mesons $P=\pi, K, \eta, \eta'$. Deuteron… read more here.

DOI: 10.1103/physrevd.99.096014

Abstract: The $\rho\rho$ scattering has been studied by two groups which both claimed a dynamical generated scalar meson, most likely to be $f_0(1370)$. Here we investigate the influence of coupled-channels of pseudoscalar mesons, i.e., $\pi\pi$ and… read more here.

DOI: 10.1134/s1063778819120159

Abstract: The expressions for the transition form factors (TFFs) of pseudoscalar mesons are derived in the context of the anomaly sum rule approach based on the dispersion representation of the axial anomaly and hypothesis of the… read more here.
