    The Schrodinger equation with Hulthen potential plus ring-shaped potential

    Full text link
    We present the solutions of the Schro¨\ddot{o}dinger equation with the Hultheˊ\acute{e}n potential plus ring-shape potential for ℓ≠0\ell\neq 0 states within the framework of an exponential approximation of the centrifugal potential.Solutions to the corresponding angular and radial equations are obtained in terms of special functions using the conventional Nikiforov-Uvarov method. The normalization constant for the Hultheˊ\acute{e}n potential is also computed.Comment: Typed with LateX,12 Pages, Typos correcte

    Relationship between sample morphology and carrier diffusion length in gan thin films

    Full text link
    Scanning and spot-mode cathodoluminescence investigations of homo-and hetero-epitaxial GaN films indicate a surprisingly small influence of their microstructure on overall intensity of a light emission. This we explain by a correlation between structural quality of these films and diffusion length of free carriers and excitons. Diffusion length increases with improving structural quality of the samples, which, in turn, enhances the rate of nonradiative recombination on structural defects, such as dislocations

    Search for long-lived particles using nonprompt jets and missing transverse momentum with proton-proton collisions at root s=13 TeV

    No full text
    A search for long-lived particles decaying to displaced, nonprompt jets and missing transverse momentum is presented. The data sample corresponds to an integrated luminosity of 137 fb(-1) of proton-proton collisions at a center-of-mass energy of 13 TeV collected by the CMS experiment at the CERN LHC in 2016-2018. Candidate signal events containing nonprompt jets are identified using the timing capabilities of the CMS electromagnetic calorimeter. The results of the search are consistent with the background prediction and are interpreted using a gauge-mediated supersymmetry breaking reference model with a gluino next-to-lightest supersymmetric particle. In this model, gluino masses up to 2100, 2500, and 1900 GeV are excluded at 95% confidence level for proper decay lengths of 0.3, 1, and 100 m, respectively. These are the best limits to date for such massive gluinos with proper decay lengths greater than similar to 0.5 m. (C) 2019 The Author. Published by Elsevier B.V
