    OPTICAL AND ELECTRICAL PROPERTIES OF ZnTe AND ZnTe: O THIN FILMS DEPOSITED BY CSVT TECHNIQUE

    No full text
    Zinc Telluride (ZnTe) thin films were deposited onto glass and CdTe substrates by CSVT (Close Space Vapor Transport) technique. The analysis of the chemical compositions for the as-deposited as well as annealed ZnTe thin films was estimated by using the method of energy dispersive analysis of x-ray (EDAX). The morphological structural, optical and electrical properties were studied

    A joint measurement is presented of the branching fractions Bs0μ+μB^0_s\to\mu^+\mu^- and B0μ+μB^0\to\mu^+\mu^- in proton-proton collisions at the LHC by the CMS and LHCb experiments. The data samples were collected in 2011 at a centre-of-mass energy of 7 TeV, and in 2012 at 8 TeV. The combined analysis produces the first observation of the Bs0μ+μB^0_s\to\mu^+\mu^- decay, with a statistical significance exceeding six standard deviations, and the best measurement of its branching fraction so far, and three standard deviation evidence for the B0μ+μB^0\to\mu^+\mu^- decay. The measurements are statistically compatible with SM predictions and impose stringent constraints on several theories beyond the SM
