The formation of the eta' in the reaction e(+)e(-)-->e(+)e(-)eta'-->e(+)e(-)pi(+)pi(-)gamma has been measured by the L3 detector at a centre-of-mass energy of 91 GeV. The radiative width of the eta' has been found to be Gamma(gamma gamma)=4.17+/-0.10(stat.)+/-0.27(sys.)keV. The Q(2) dependence of the eta' formation cross section has been measured for Q(2) less than or equal to 10 GeV2 and the eta' electromagnetic transition form factor has been determined. The form factor can be parametrised by a pole form with Lambda=0.900+/-0.046(stat.)+/-0.022(sys.)GeV. It is also consistent with recent non-perturbative QCD calculations.

Abstract

The formation of the eta' in the reaction e(+)e(-)-->e(+)e(-)eta'-->e(+)e(-)pi(+)pi(-)gamma has been measured by the L3 detector at a centre-of-mass energy of 91 GeV. The radiative width of the eta' has been found to be Gamma(gamma gamma)=4.17+/-0.10(stat.)+/-0.27(sys.)keV. The Q(2) dependence of the eta' formation cross section has been measured for Q(2) less than or equal to 10 GeV2 and the eta' electromagnetic transition form factor has been determined. The form factor can be parametrised by a pole form with Lambda=0.900+/-0.046(stat.)+/-0.022(sys.)GeV. It is also consistent with recent non-perturbative QCD calculations.
