Global analyses of effective Higgs portal dark matter models in the frequentist and Bayesian statistical frameworks are presented and DDCalc2.0, a tool for calculating direct detection observables and likelihoods for arbitrary non-relativistic effective operators is presented.
Model-independent analysis of the DAMPE excess
A bstractThe Dark Matter Particle Explorer (DAMPE) recently released measurements of the electron spectrum with a hint of a narrow peak at about 1.4 TeV. We investigate dark matter (DM) models that…
Superplot: a graphical interface for plotting and analysing MultiNest output
An application, Superplot, for calculating and plotting statistical quantities relevant to parameter inference from a “chain” of samples drawn from a parameter space, produced by, e.g., MultiNest.
Bubbleprofiler: Finding the field profile and action for cosmological phase transitions
Combined collider constraints on neutralinos and charginos
Searches for supersymmetric electroweakinos have entered a crucial phase, as the integrated luminosity of the Large Hadron Collider is now high enough to compensate for their weak production…
Constrained MSSM favoring new territories: the impact of new LHC limits and a 125 GeV Higgs boson
We present an updated and extended global analysis of the Constrained MSSM (CMSSM) taking into account new limits on supersymmetry from ~5/fb data sets at the LHC. In particular, in the case of the…
Dark matter and collider signatures of the MSSM
We explore the MSSM with 9 free parameters (p9MSSM) that have been selected as a minimum set that allows an investigation of neutralino dark matter and collider signatures while maintaining…
Naturalness of the relaxion mechanism
A bstractThe relaxion mechanism is a novel solution to the hierarchy problem. In this first statistical analysis of the relaxion mechanism, we quantify the relative plausibility of a QCD and a…
