Measurement of the form-factor ratios for D+ -> K*0e+νe
Fermilab E791 Collaboration, E. M. Aitala
Abstract
We present a measurement of the form-factor ratios rV=V(0)/A1(0) and r2=A2(0)/A1(0) for the decay D+ -> K*0 e+ νe. The measurement is based on a signal of approximately 3000 D+ -> K*0 e+ νe, K*0 -> K-π+ decays reconstructed in data from charm hadroproduction experiment E791 at Fermilab. The results are rV = 1.84 +- 0.11 +- 0.08 and r2 = 0.71 +- 0.08 +- 0.09.
