چکیده
A search for charmed baryons decaying to D(0)p reveals two states: the Lambdac(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(-)pi(+) and K(-)pi(+)pi(-)pi(+) 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 Lambdac(2880)+ baryon and relative yield of the two baryons are also measured.

Pentaquark Searches in H1
We report on searches in deep inelastic ep scattering for narrow baryonic states decaying into Ξ − π − , Ξ − π + , K 0 S p and their charge conjugates, at centre-of-mass energies of 300 and 318 GeV. No signal for a new narrow baryonic state is observed in the mass ranges 1600-2100 MeV (Ξπ) and from threshold up to 1700 MeV (K 0 S p). The standard baryon Ξ(1530) 0 is observed in the decay mode Ξ...

Results are presented for the 500 GeV/c pion production asymmetry and polarization of the Λ c (Λ c) charmed baryon from Fermilab experiment E791. An analysis of the decay to the pKπ final state is described. Resonant sub-channel fractions and phases are given and possible resonant effects in the low mass pK system discussed. Significant decay to Λ c → ∆ ++ K − establishes for the first time the...
متن کاملPentaquark Searches at Cdf * Dmitry O. Litvintsev a (for Cdf Collaboration)
Searches for states, characterized by so-called exotic quantum numbers, i.e., quantum numbers that cannot be obtained from minimal (qq̄) or (qqq) configurations of standard mesons and baryons, have taken place since the introduction of QCD and quark model. Until recently, these searches yielded very little conclusive evidence for such states. During 2003, however, the situation has changed drama...
متن کاملSum rules for charmed baryon masses.
The measured masses of the three charge states of the charmed Σc baryon are found to be in disagreement with a sum rule based on the quark model, but relying on no detailed assumptions about the form of the interaction. This poses a significant problem for the charmed baryon sector of the quark model. Other relations among charmed baryon masses are also discussed. PACS numbers: 12.40.Yx., 14.20...
متن کاملNew Predictions for Multiquark Hadron Masses
The recent reported charmed-strange resonance at 2.32 GeV/c suggests a possible multiquark state. Three types of multiquark bound states are reviewed. A previous model-independent variational approach considers a tetraquark with two heavy antiquarks and two light quarks as a heavy antidiquark with the color field of a quark bound to the two light quarks with a wave function like that of a heavy...

Charmed meson resonances with quantum numbers J P = 0 + and J P = 1 + are generated in terms of chiral coupled-channel dynamics. At leading order in the chiral expansion a parameter-free prediction is obtained for the scattering of Goldstone bosons off charmed pseudo-scalar and vector mesons. The recently announced narrow open charm states observed by the BABAR and CLEO collaborations are repro...
