Study of the Form Factor Using the SND Detector

Study of the Form Factor Using the SND Detector

In this paper, we present the form factor measurement in the virtual photon mass range 1 GeV < < 2 GeV in the process. Measurements are based on the data acquired by the SND detector at the VEPP-2000 collider in Novosibirsk. The obtained form factor is approximated in the vector meson dominanc...

Zusammenfassung:In this paper, we present the form factor measurement in the virtual photon mass range 1 GeV < < 2 GeV in the process. Measurements are based on the data acquired by the SND detector at the VEPP-2000 collider in Novosibirsk. The obtained form factor is approximated in the vector meson dominance (VMD) model. The joint fitting of the form factor obtained in the SND and NA60 experiments is also performed.
