Study of the process e+e−→pp¯ in the c.m. energy range from threshold to 2 GeV with the CMD-3 detector

Using a data sample of 7.7 pb−1 collected with the CMD-3 detector at the VEPP-2000 e+e− collider we select about 2900 events of the process e+e−→pp¯ and measure its cross section at 12 energy points with about 6% systematic uncertainty. From the angular distribution of produced nucleons we obtain th...
