Pion pair production in photon-photon collisions

Abstract

The process γγ→π+π was measured using the detector MD-1 at VEPP-4. The two-photon reactionse + e , μ+ μ and π+ π pair production were separated using scintillation counters, Cherenkov counters and shower-range chambers. A radiation widthГ γγ(f 2(1270))=3.1±0.35±0.35 keV was obtained.
