Abstract
A search for charmed baryons decaying to reveals two states: the baryon and a previously unobserved state at a mass of and with an intrinsic width of . Consistent and significant signals are observed for the and decay modes of the in annihilation data recorded by the BABAR detector at a center-of-mass energy of 10.58 GeV. There is no evidence in the spectrum of doubly charged partners. The mass and intrinsic width of the baryon and relative yield of the two baryons are also measured.
