Radiative return meets GVMD
Pau Petit Rosàs, Olga Shekhovtsova, William J. Torres Bobadilla
We improve the description of pion-photon interactions in the radiative return process at the next-to-leading order by including the pion form factor in the Fey…

Analytical Inverse QCD Coupling Constant approach and its result for
Malaspina R., Pierini L., Shekhovtsova O. +1
We propose a model for the QCD running coupling constant based on the Analytical Inverse QCD Coupling Constant concept with an additional regularization in the low momentum region.…

Microscopic parametrization of the near threshold oscillations of the nucleon time-like effective electromagnetic form factors
Francesco Rosini, Simone Pacetti, Olga Shekhovtsova +1
We present an analysis of the recent near threshold BESIII data for the nucleon time-like effective form factors. The damped oscillation emerging from the subtraction of the dipole…
