Abstract

The dynamics of the decay Ds+ → φe+ve are studied using a sample of 474 events recorded by the CLEO II detector. A three dimensional fit to the decay angles and q2 is performed to extract the ratios of form factors R2=A2(0)/A1(0) and Rv=V(0 )/ A1(0), where A1(0) and A2(0) are the two axial vector form factors and V(0) is the vector form factor evaluated at q2 =0. By assuming the single pole parameterization for the form factors, we obtain: R2=1.4±0.5±0.3 and Rv=0.9±0.6±0.3.
