Model Independent Measurement of Form Factors in the Decay D+ --> K- pi+ e+ nue
Abstract
We present model independent measurements of the helicity basis form factors in the decay D+ -> K- pi+ e+ nue obtained from about 2800 decays reconstructed from a 281 pb-1 data sample collected at the psi(3770) center-of-mass energy with the CLEO-c detector. We confirm the existence of a previously observed spin-zero K- pi+ component interfering with the K*0bar amplitude. We see no evidence for additional d- or f-wave contributions.
