The semi-constrained NMSSM satisfying bounds from the LHC, LUX and Planck
Ellwanger, Ulrich; Hugonie, Cyril
We study the parameter space of the semi-constrained NMSSM, compatible with constraints on the Standard Model like Higgs mass and signal rates, constraints from searches for squarks and gluinos, a dark matter relic density compatible with bounds from WMAP/Planck, and direct detection cross sections compatible with constraints from LUX. We consider…
Annihilation signals from asymmetric dark matter
Hardy, Edward; Lasenby, Robert; Unwin, James
In the simplest models of asymmetric dark matter (ADM) annihilation signals are not expected, since the DM is non-self-conjugate and the relic density of anti-DM is negligible. We investigate a new class of models in which a symmetric DM component, in the `low-mass' 1-10 GeV regime favoured for linking the DM and baryon asymmetries, is repopulated…
Statistical tests of sterile neutrinos using cosmology and short-baseline data
Bergström, Johannes; Gonzalez-Garcia, M. C.; Niro, V. +1 more
In this paper we revisit the question of the information which cosmology provides on the scenarios with sterile neutrinos invoked to describe the SBL anomalies using Bayesian statistical tests. We perform an analysis of the cosmological data in ΛCDM+ r + ν s cosmologies for different cosmological data combinations, and obtain the marg…
