Limits for the central production of Theta^+ and Xi^{--} pentaquarks in 920 GeV pA collisions

B Collaboration, I. Abt

We have searched for Theta^+(1540) and Xi^{--}(1862) pentaquark candidates in proton-induced reactions on C, Ti and W targets at mid-rapidity and \sqrt{s} = 41.6 GeV. In 2x10^8 ine…

First observation of a narrow charm-strange meson DsJ(2632) -> Ds eta and D0 K+

The SELEX Collaboration, A. V. Evdokimov

We report the first observation of a charm-strange meson DsJ(2632) at a mass of 2632.6+/-1.6 MeV/c^2 in data from SELEX, the charm hadro-production experiment E781 at Fermilab. Thi…

Confirmation of the Double Charm Baryon Xi_cc+ via its Decay to p D+ K-

The SELEX Collaboration, A. Ocherashvili, M. A. Moinester +3

We observes a signal for the double charm baryon Xi_cc+ in the charged decay mode Xi_cc+ -> p D+ K- to complement the previously reported decay Xi_cc+ -> Lambda_c K- pi+ in data fr…

Search for the exotic Resonance in 340GeV/c -Nucleus Interactions

WA89 Collaboration

We report on a high statistics search for the resonance in -nucleus collisions at 340GeV/c. No evidence for this resonance is found in our data sample which con…

Upper limit on the decay Sigma(1385)- --> Sigma- gamma, and cross section for gamma Sigma- --> Lambda pi-

SELEX Collaboration, V. V. Molchanov

Coherent Lambda pi- production on Pb of 600 GeV Sigma- hyperons has been studied with the SELEX facility at Fermilab. Using the Primakoff formalism, we set a 90% CL upper limit on…
