Observation of a new charmed strange meson
Abstract
Using the CLEO II detector, we have obtained evidence for a new meson decaying to D0K+. Its mass is 2573.2+1.7-1.6+/-0.8+/-0.5 MeV/c2 and its width is 16+5-4+/-3 MeV/c2. Although we do not establish its spin and parity, the new meson is consistent with predictions for an L=1, S=1, JP=2+ charmed strange state.
