First results of spherical neutral detector (SND) experiments at VEPP-2000

Preliminary results of the first experiments at the new VEPP-2000 e+e− collider are presented. The experiments have been carried out in the center of mass energy range 1-2 GeV with instant luminosity 1030-1031cm−2s−1 and total integrated luminosity of about 10pb−1. The main e+e− annihilation cross sections, π+π−π0π0,π+π−π0,π0π0γ,andπ+π−η, have been measured. The cross section of nucleon-antinucleon production is also presented.
