Abstract

Using data recorded by the CLEO-II detector at Cornell Electron Storage Ring (CESR), we report the first observation of a narrow state decaying into c+. The state has mass difference M(c+)-M(c+) of 178.2 0.5 1.0 MeV/c2, and a width of <5.5 MeV/c2 (90% confidence level limit). The most likely explanation of this new state is that it is the c*0, the JP=32+ spin excitation of the c0 charmed baryon. © 1995 The American Physical Society.
