چکیده

The Ξ_{c}^{+}K^{-} mass spectrum is studied with a sample of pp collision data corresponding to an integrated luminosity of 3.3  fb^{-1}, collected by the LHCb experiment. The Ξ_{c}^{+} is reconstructed in the decay mode pK^{-}π^{+}. Five new, narrow excited Ω_{c}^{0} states are observed: the Ω_{c}(3000)^{0}, Ω_{c}(3050)^{0}, Ω_{c}(3066)^{0}, Ω_{c}(3090)^{0}, and Ω_{c}(3119)^{0}. Measurements of their masses and widths are reported.

Results and Perspectives in Particle Physics,

Recent measurements in the charm sector at BABAR are reviewed. The scope of the presentation includes the observation of two new narrow mesons in the D + s π 0 and D + s π 0 γ final states as well as the measurement of D 0-D 0 mixing parameters by means of two methods: using the doubly-Cabibbo-suppressed D 0 decay to K + π − and using the ratios of lifetimes extracted from samples of D 0 mesons...

Pentaquark 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...

Observation of the Decay Ξ_{b}^{-}→pK^{-}K^{-}.

Decays of the Ξ_{b}^{-} and Ω_{b}^{-} baryons to the charmless final states ph^{-}h^{'-}, where h^{(')} denotes a kaon or pion, are searched for with the LHCb detector. The analysis is based on a sample of proton-proton collision data collected at center-of-mass energies sqrt[s]=7 and 8 TeV, corresponding to an integrated luminosity of 3  fb^{-1}. The decay Ξ_{b}^{-}→pK^{-}K^{-} is observed wit...

Search for Baryon-Number Violating Ξ_{b}^{0} Oscillations.

A search for baryon-number violating Ξ_{b}^{0} oscillations is performed with a sample of pp collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 3  fb^{-1}. The baryon number at the moment of production is identified by requiring that the Ξ_{b}^{0} come from the decay of a resonance Ξ_{b}^{*-}→Ξ_{b}^{0}π^{-} or Ξ_{b}^{'-}→Ξ_{b}^{0}π^{-}, and the baryon n...

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...
