Abstract

We determine the weak coupling [Formula presented] between the [Formula presented] and [Formula presented] quarks using a sample of [Formula presented] [Formula presented] events in the CLEO detector at the Cornell Electron Storage Ring. We determine the yield of reconstructed [Formula presented] decays as a function of [Formula presented], the boost of the [Formula presented] in the [Formula presented] rest frame, and from this we obtain the differential decay rate [Formula presented]. By extrapolating [Formula presented] to [Formula presented], the kinematic end point at which the [Formula presented] is at rest relative to the [Formula presented], we extract the product [Formula presented], where [Formula presented] is the form factor at [Formula presented]. Combined with theoretical results for [Formula presented] we determine [Formula presented].
