Using data collected by the HERA-B experiment, we have measured the fraction of J/ψ's produced via radiative χ c decays in interactions of 920 GeV protons with carbon and titanium targets. We obtained R χ c = 0. fraction of J/ψ from χ c decays averaged over proton–carbon and proton–titanium collisions. This result is in agreement with previous measurements(More)
We have searched for Theta+(1540) and Xi(--)(1862) pentaquark candidates in proton-induced reactions on C, Ti, and W targets at midrapidity and square root of s = 41.6 GeV. In 2 x 10(8) inelastic events we find no evidence for narrow (sigma approximately 5 MeV) signals in the Theta+ --> pK0(S) and Xi(--) --> Xi- pi- channels; our 95% C.L. upper limits (UL)(More)
This article analyzes the pasture flora of the Kyzyl Kum Desert. The distribution of fodder plants is analyzed in terms of biotopes, biomorphs, and edibility. The arealogical analysis of the pasture flora of Kyzyl Kum showed that it is characterized by Ancient Mediterranean genesis and has genetic ties to the Iranian, Caucasian, North Central Asian, and(More)
