A search for charmed baryons decaying to D{sup 0}p reveals two states: the {Lambda}{sub c}(2880){sup +} baryon and a previously unobserved state at a mass of [2939.8 {+-} 1.3 (stat.) {+-} 1.0 (syst.)] MeV/c{sup 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{sup -}{pi}{sup +} and K{sup -}{pi}{sup +}{pi}{sup -}{pi}{sup +} decay modes of the D{sup 0} in 287 fb{sup -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{sup +}p spectrum of doubly-charged partners. The mass and intrinsic width of the {Lambda}{sub c}(2880){sup +} baryon and relative yield of the two baryons are also measured.

Using data recorded by the CLEO-II detector at CESR, they report the first observation of an excited charmed baryon decaying into [Xi]{sub c}°[pi]. The state has mass difference M([Xi]{sub c}°[pi]) = M([Xi]{sub c}°) of 174.3 ± 0.5 ± 1.0 MeV/c2, and a width of

Download First Observation of Doubly Charmed Baryons Book in PDF, ePub and Kindle
The SELEX experiment (E781) at Fermilab has observed two statistically compelling high mass states near 3.6 GeV/c2, decaying to?{sub c} K−?+ and?{sub c}+ K−?+?+. These final states are Cabibbo-allowed decay modes of doubly charmed baryons?{sub cc}+ and?{sub cc}{sup ++}, respectively. The masses are in the range expected from theoretical considerations, but the spectroscopy is surprising. SELEX also has weaker preliminary evidence for a state near 3.8 GeV/c2, a high mass state decaying to?{sub c}+ K−?+?+, possibly an excited?{sub cc}{sup ++} (ccu*). Data are presented and discussed.

Download Production and Decay of the Lambda C Charmed Baryon from Fermilab E791 Book in PDF, ePub and Kindle
Results are presented for the 500 GeV/c pion production asymmetry and polarization of the[Lambda][sub c] ([bar[Lambda]][sub c]) charmed baryon from Fermilab experiment E791. An analysis of the decay to the p[bar K][pi] final state is described. Resonant sub-channel fractions and phases are given and possible resonant effects in the low mass p[bar K] system discussed. Significant decay to[Lambda][sub c][yields][Delta][sup 2]K[sup -] establishes for the first time the importance of a W exchange mechanism in charmed baryon decay.
