Abstract
Using the decay sequence J/{Psi} {yields} {gamma}X, X {yields} {alpha}{sup {+-}}{sub 0}(980) {pi}{sup -+}, a{sup {+-}}{sub 0}(980 ) {yields} {eta}{pi}{sup {+-}}, where X is the f{sub 1}(1285) or {eta}(1400), the {eta}{pi}{sup +} vs. {eta}{pi}{sup -} Dalitz plot intensity distributions are fitted with a model containing a coupled-channel parametrization of the a{sub 0}(980). Preliminary values for the spin of X, the mass and width of the a{sup {+-}}{sub 0}(980) to {eta}{pi}{sup {+-}}, and the ratio of a{sup +}{sub 0}(980) coupling strengths, {delta}{sup 2}{sub K} / {delta}{sup 2}{sub {eta}}, to anti K{sup 0}K{sup +} and {eta}{pi}{sup +} are determined. From this model, the predictions for the ratios of branching ratios r{sub X} = B(X {yields} a{sub 0}(980){pi}).B(a{sub 0}(980) {yields} Kanti K) / B(X {yields} a{sup {+-}}{sub 0}(980){pi}).B(a{sup {+-}}{sub 0}(980) {yields} {eta}{pi}{sup {+-}}) are compared with those obtained from MARK III Partial Waves analyses of the decays J/{Psi}{yields}{gamma}K{sup 0}{sub s}K{sup {+-}}{pi}{sup -+} and J/{Psi} {yields} {gamma}{eta}{pi}{sup +}{pi}{sup -}.
