Abstract:

We present new measurements of the branching ratios and decay distributions for the decays D+->K*0barl+nu. We observe an asymmetry in the K*0bar angular decay distribution that we interpret as evidence for a previously unobserved s-wave K-Pi+ amplitude that interferes with the K*0bar. These measurements are taken from the data collected by the Fermilab charm photoproduction experiment E831(FOCUS) during 1996-97.
