Observation of the production of η mesons in two-photon collisions

Physical Review D, Volume 28, No. 11, Year 1983

Using 2674 nb-1 of data taken at s from 5.00 to 7.25 GeV with a trigger sensitive to decays of lower-mass particles produced in two-photon collisions, we have observed 56±12 events consistent with the reaction e+e-→e+e-η, η→γγ. Background has been subtracted using separated-beam data. We obtain Γγγ(η)=0.56±0. 16 keV and the pseudoscalar-nonet mixing angle θP=-17.6°±3. 6°. © 1983 The American Physical Society.
