Recent results on e +e − annihilation to hadrons in the SND experiment

Recent results of the SND experiment at the VEPP-2000 collider on e +e − annihilation to hadrons below 2 GeV are presented. In particular, we discuss measurements of the e +e − → π +π − and e +e − → nn¯ cross sections. The processes e +e − → π +π −π 0 , K+K−π 0 , ηπ0 γ and 2ηγ were under investigati...

Zusammenfassung:	Recent results of the SND experiment at the VEPP-2000 collider on e +e − annihilation to hadrons below 2 GeV are presented. In particular, we discuss measurements of the e +e − → π +π − and e +e − → nn¯ cross sections. The processes e +e − → π +π −π 0 , K+K−π 0 , ηπ0 γ and 2ηγ were under investigation as well. The preliminary results on the e +e − → ωπ0 → π +π −2π 0 cross section measurement are also presented.
