Abstract:

The solar neutrino capture rate measured by the Russian-American Gallium Experiment on a metallic gallium target SAGE during the time from January 1990 through December 2000 is 77.0-6.2-3.0+6.2+3.5 SNU, where the uncertainties are statistical and systematic, respectively. The experimental procedures and data analysis are presented. © 2002 MAIK. "Nauka/Interperiodica".

Abstract:

The R-parity violating decay of the neutralino X̃10 into a moun and two jets in 77.5 pb-1 of data was searched. For tanβ=2, squark masses below 240 GeV/c2 and gluino masses below 224 GeV/c2 were exluded. For equal masses of squarks and gluinos, the mass limit was 265 GeV/c2. These limits were found to be comparable to those achieved previously in complementary channels.

Abstract:

We report on measurements of the branching ratios of the decays B+→Xcl0(1P)K+ and B+ →J/ψK+π+π-, where Xcl0(1P)→J/ψγ and J/ψ→μ+μ- in pp collisions at √s= 1.8 TeV. Using a data sample from an integrated luminosity of 110 pb-1 collected by the Collider Detector at Fermilab we measure the branching ratios to be BR(B+→Xcl0(1P) K+)=15.5±5.4(stat)±1.5(syst)±1.3(br)× 10-4 and BR(B+ →J/ψK+π+π-)=6.9 ±1.8(stat)±1.1(syst)±0.4(br)×10-4 where (br) is due to the finite precision on BR(B-→J/ψK+), BR(Xcl0(1P)→J/ψγ)is used to normalize the signal yield, and (syst) encompasses all other systematic uncertainties.
