Abstract: | A search for charmed baryons decaying to D 0 p reveals two states: the Λ c ( 2880 ) + baryon and a previously unobserved state at a mass of [ 2939.8 ± 1.3 ( stat ) ± 1.0 ( syst ) ] MeV / c 2 and with an intrinsic width of [ 17.5 ± 5.2 ( stat ) ± 5.9 ( syst ) ] MeV . Consistent and significant signals are observed for the K − π + and K − π + π − π + decay modes of the D 0 in 287 fb − 1 annihilation data recorded by the BABAR detector at a center-of-mass energy of 10.58 GeV. There is no evidence in the D + p spectrum of doubly charged partners. The mass and intrinsic width of the Λ c ( 2880 ) + baryon and relative yield of the two baryons are also measured. |
