Observation of Two Narrow States Decaying into ${\Xi }_c^{+}\gamma$ and ${\Xi }_c^0\gamma$

C. P. Jessop

We report the first observation of two narrow charmed strange baryons decaying to ${\Xi }_c^{+}\gamma$ and ${\Xi }_c^0\gamma$, respectively, using data from the CLEO II detector at CESR. We interpret th…
