Abstract

A high performance apparatus has been designed and built by the H8-RD22 collaboration for the study of channeling and volume reflection phenomena in the interaction of 400 GeV/c protons with bent silicon crystals, during the 2006 data taking in the external beamline H8 of the CERN SPS. High-quality silicon short crystals were bent by either anticlastic or quasimosaic effects. Alignment with the highly parallel (8 murad divergence) proton beam was guaranteed through a submicroradian goniometric system equipped with both rotational and translational stages. Particle tracking was possible by a series of silicon microstrip detectors with high-resolution and a parallel plate gas chamber, triggered by various scintillating detectors located along the beamline. Experimental observation of volume reflection with 400 GeV/c protons proved true with a deflection angle of (10.4+/-0.5) murad with respect to the unperturbed beam, with a silicon crystal whose (111) planes were parallel to the beam.

Abstract

We report the first observation of a charm-strange meson D(+)(sJ)(2632) at a mass of 2632.5+/-1.7 MeV/c(2) in data from SELEX, the charm hadro-production experiment E781 at Fermilab. This state is seen in two decay modes, D(+)(s)eta and D0K+. In the D(+)(s)eta decay mode we observe a peak with 101 events over a combinatoric background of 54.9 events at a mass of 2635.4+/-3.3 MeV/c(2). There is a corresponding peak of 21 events over a background of 6.9 at 2631.5+/-2.0 MeV/c(2) in the decay mode D0K+. The decay width of this state is <17 MeV/c(2) at 90% confidence level. The relative branching ratio Gamma(D0K+)/Gamma(D(+)(s)eta) is 0.14+/-0.06. The mechanism that keeps this state narrow is unclear. Its decay pattern is also unusual, being dominated by the D(+)(s)eta decay mode.

Abstract

Novel 9,11-ethano analogues of prostaglandin endoperoxides with a nitrogen in position 13 were synthesized. (1)H NMR spectra of the obtained compounds were studied. All prostanoids administered perorally at doses of 2.5-10.0 microg x kg(-1) had specific dose-dependent effects on the B-cellular immunity estimated under in vivo conditions on the model of the B-cellular immune response. In terms of the direction of their activities, eight of the studied compounds were found to be immunostimulators, whereas other three compounds displayed immunosuppressing effect. Two of the compounds increased the amount of antibody-forming cells (AFC) per 10(6) spleen cells by 1.9 times in comparison with the respective parameter of control group.

Abstract

We observe a signal for the doubly charmed baryon Xi(+)(cc) in the charged decay mode Xi(+)(cc)-->Lambda(+)(c)K-pi(+) in data from SELEX, the charm hadroproduction experiment at Fermilab. We observe an excess of 15.9 events over an expected background of 6.1+/-0.5 events, a statistical significance of 6.3sigma. The observed mass of this state is 3519+/-1 MeV/c(2). The Gaussian mass width of this state is 3 MeV/c(2), consistent with resolution; its lifetime is less than 33 fs at 90% confidence.

Abstract

We report the first observation of the Cabibbo-suppressed charm baryon decay Ξ&#95;{c}^{+}→pK^{-}π^{+}. We observe 150±22±5 events for the signal. The data were accumulated using the SELEX spectrometer during the 1996-1997 fixed target run at Fermilab, chiefly from a 600 GeV/c Σ^{-} beam. The branching fractions of the decay relative to the Cabibbo-favored Ξ&#95;{c}^{+}→Σ^{+}K^{-}π^{+} and Ξ&#95;{c}^{+}→Ξ^{-}π^{+}π^{+} are measured to be B(Ξ&#95;{c}^{+}→pK^{-}π^{+})/B(Ξ&#95;{c}^{+}→Σ^{+}K^{-}π^{+})=0.22±0.06±0.03 and B(Ξ&#95;{c}^{+}→pK^{-}π^{+})/B(Ξ&#95;{c}^{+}→Ξ^{-}π^{+}π^{+})=0.20±0.04±0.02, respectively.

Abstract

In in vitro experiments on a model of arachidonate- and thrombin-induced platelet aggregation, analogues of PG endoperoxides displayed an antiaggregatory effect or stimulated spontaneous platelet aggregation in the whole blood of man and rabbits, but a slight antiaggregatory effect in the rabbit intact organism. The presence of the hydroxyl group instead of the routine alkyl omega-chain produced an antiaggregatory effect due to TxA2 receptor blockade.
