Supersymmetric dark matter after LHC run 1
Different mechanisms operate in various regions of the MSSM parameter space to bring the relic density of the lightest neutralino, [Formula: see text], assumed here to be the lightest SUSY particle (LSP) and thus the dark matter (DM) particle, into the range allowed by astrophysics and cosmology. These mechanisms include coannihilation with some nearly degenerate next-to-lightest supersymmetric...
متن کاملThe pMSSM10 after LHC run 1
We present a frequentist analysis of the parameter space of the pMSSM10, in which the following ten soft SUSY-breaking parameters are specified independently at the mean scalar top mass scale [Formula: see text]: the gaugino masses [Formula: see text], the first-and second-generation squark masses [Formula: see text], the third-generation squark mass [Formula: see text], a common slepton mass [...
متن کاملSupersymmetric Dark Matter 2004 *
Recent cosmological data allow to determine the universal Dark Matter (DM) density to a precision of about 10%, if a simple, well–motivated ansatz for the spectrum of primordial density perturbations is correct. Not surprisingly, a thermal neutralinõ χ 0 1 will have the correct relic density only in " small " regions of parameter space. In particular, for fixed values of the other parameters, t...
متن کاملThe NUHM2 after LHC Run 1
We make a frequentist analysis of the parameter space of the NUHM2, in which the soft supersymmetry (SUSY)-breaking contributions to the masses of the two Higgs multiplets, [Formula: see text], vary independently from the universal soft SUSY-breaking contributions [Formula: see text] to the masses of squarks and sleptons. Our analysis uses the MultiNest sampling algorithm with over [Formula: se...
متن کاملOn Supersymmetric Dark Matter
The extra particles provided by Supersymmetry(SUSY) appear as natural candidates for exotica such as the missing Dark Matter of the Universe. The particle candidates for Dark Matter, and the basic elements of the minimal supersymmetric extension of the Standard Model are reviewed. The needed elements to compute the neutralino counting rate are given, considering new Yukawa loop corrections to t...
