abstract
Using data recorded by the CLEO II detector at the Cornell Electron Storage Ring, we report evidence for two new charmed baryons, one decaying into +c+ via an intermediate *0c and its isospin partner decaying into 0c+ via an intermediate *+c. We measure the mass differences of the two states to be M(+c+)M(+c)=348.60.61.0 MeV, and M(0c+) M(0c)=347.20.72.0 MeV. We interpret these new states as the JP = 3/2 c1 particles, the charmed-strange analogs of the +c1(2625). 1999 The American Physical Society.
