Abstract: (arXiv)

Using data recorded with the CLEO II and CLEO II.V detector configurations at the Cornell Electron Storage Rings, we report the first observation and mass measurement of the

\Sigma_c^{*+}

charmed baryon, and an updated measurement of the mass of the

\Sigma_c^+

baryon. We find

M(\Sigma_c^{*+})-M(\Lambda_c^+)

= 231.0 +- 1.1 +- 2.0 MeV, and

M(\Sigma_c^{+})-M(\Lambda_c^+)

= 166.4 +- 0.2 +- 0.3 MeV, where the errors are statistical and systematic respectively.
