Aubert, B. et al. (2007) Observation of a Charmed Baryon Decaying to D0p at a Mass Near 2.94 GeV/c2. Physical Review Letters, 98 (1). 012001. ISSN 0031-9007Metadata only available from this repository.
A search for charmed baryons decaying to D0p reveals two states: the Λc(2880)+ baryon and a previously unobserved state at a mass of [2939.8±1.3(stat)±1.0(syst)] MeV/c2 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 D0 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 Λc(2880)+ baryon and relative yield of the two baryons are also measured.
