Hadronic vacuum polarization and e+e- to m+m- cross section: Reanalysis with new precise data for Sigma-h with 4pi final states included
Popis výsledku v původním jazyce
The interference effect between leptonic radiative corrections and hadronic polarization functions is calculated via optical theorem for m−pair production in vicinity of narrow resonances. Within seven most dominant exclusive channels of the production cross section Sigma h(e+e- to hadrons) one achieves high acuracy which is necessary for the comparison with experiments. The result is compared with KLOE and KLOE2 experiments for m-m+ and m-m+gamma productions at psi and omega/rho meson energy.
