Abstract
The processes psi(2S) --> gamma pi(+)pi(-), gamma K+K-, and gamma p (p ) over bar have been studied using a sample of 3.79 x 10(6) psi(2S) de cays. We determine the total width of the chi(c0) to be Gamma(chi c0)( tot) = 14.3 +/- 2.0 +/- 3.0 MeV. We present the first measurement of t he branching fraction B(chi(c0) --> p (p) over bar) = (15.9 1 4.3 i 5. 3) x 10(-5) where the first error is statistical and the second one is systematic. Branching fractions of chi(c0,2) --> pi(+)pi(-) and K+K- are also reported. [S0031-9007(98)07355-4].
