New parametrisation for the electric and the magnetic form factors of proton and neutron are presented. The proton form factors describe well the recent measurements by BaBar collaboration and earlier ones of the ratio of the form factors in space-like region. The neutron form factors are consistent with earlier measurements of neutron pair production and ratio of the form factors in the space-like region. These form factors are implemented into the generator PHOKHARA, which simulates the…

Study of the process e+e−→pp¯ via initial state radiation at BESIII

The Born cross section for the process e+e-→pp¯ is measured using the initial state radiation technique with an undetected photon. This analysis is based on datasets corresponding to an integrated

Measurement of Proton Electromagnetic Form Factors in e^{+}e^{-}→pp[over ¯] in the Energy Region 2.00-3.08 GeV.

The Born cross section of e^{+}e^{-}→pp[over ¯] is measured with the energy-scan technique and it is found to be consistent with previously published data, but with much improved accuracy.

Radiative corrections in proton–antiproton annihilation to electron–positron and their application to the PANDA experiment

Radiative corrections to the annihilation of proton–antiproton into electron–positron are revisited, including virtual and real (soft and hard) photon emission. This issue is relevant for the

Monte Carlo generators for hadron physics: updates on PHOKHARA and EKHARA generators

A short review of current upgrades of the PHOKHARA and EKHARA generators is presented together with a report on the work in progress. The upgrades are based on a newly constructed model of the χ c i

Hadronic footprint of GeV-mass dark matter

GeV-scale dark matter is an increasingly attractive target for direct detection, indirect detection, and collider searches. Its annihilation into hadronic final states produces a challenging zoo
