Pion pair production in photon-photon collisions

Creators

Description

The process γγ→π+π- has been measured with the detector MD-1 at VEPP-4. The two-photon reactions of e+e-, μ+μ- and π+π- pair production were separated using scintillation counters, Cherenkov counters and shower-range chambers. The radiation width Γγγ f2(1270)=3.1±0.35±0.35 keV has been obtained. 27 refs.; 9 figs
