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 12 GeV with instant luminosity 10 3010 31cm -2s -1 and total integrated luminosity of about 10pb -1. The main e+e- annihilation cross sections, π+π- π0π0, π+π- π0, π0π0γ,and π+π-η, have been measured. The cross section of nucleonantinucleon production is also presented. © 2012 Elsevier B.V.
