Study of χ production properties at the cern intersecting storage rings
Abstract
The inclusive production of electron pairs with and without additional photons was measured at the CERN Intersecting Storage Rings (ISR). The investigation of J/ψ particles with associated photons indicated that 47 +/- 8% of the J/ψ were produced via the photonic decay of one of the χ(3.5) states. The upper limit of the production cross-section ratio times the branching ratio into electron pairs of ψ' relative to J/ψ was found to be 2% at centre-of-mass energy of √=62 GeV
