Description
We present the first measurement of the D*+ width using 9/fb of e+e- data collected near the Υ(4S) resonance by the CLEO II.V detector. Our method uses advanced tracking techniques and a reconstruction method that takes advantage of the small vertical size of the CESR beam spot to measure the energy release distribution from the D*+→D0π+ decay. We find Γ(D*+)=96±4 (statistical)±22 (systematic) keV. We also measure the energy release in the decay and compute Δm≡mD*+-mD0=145.412±0.002 (statistical)±0.012 (systematic) MeV/c2
