Scientific paper

We report on an exclusive search for the X(3872) state in the decay pi+ pi- J/psi, J/psi to l+ l- (l = e, mu) from untagged gamma-gamma fusion and initial state radiation production using a 15.1 fb-1 data sample with the CLEO III detector. By taking advantage of the unique pi+ pi- J/psi decay kinematics, separate measurements for each production process are obtained. No signals are observed and preliminary upper limits have been established as [(2J+1)*Width_gamgam(X(3872))*BR(X(3872) to pi+ pi- J/psi)] < 12.9 eV and [Width_ee(X(3872))*BR(X(3872) to pi+ pi- J/psi)] < 8.0 eV, both at a 90% confidence level.
