Minimal Spin-one Isotriplet Dark Matter
Alexander Belyaev, Giacomo Cacciapaglia, James McKay +2
In this work we present a simple extension of the Standard Model that contains, as the only new physics component, a massive spin-one matter field in the adjoint representation of…
Impact of vacuum stability, perturbativity and XENON1T on global fits of and scalar singlet dark matter
Peter Athron, Jonathan M. Cornell, Felix Kahlhoefer +3
Scalar singlet dark matter is one of the simplest and most predictive realisations of the WIMP (weakly-interacting massive particle) idea. Although the model is constrained from al…
Two-loop mass splittings in electroweak multiplets: winos and minimal dark matter
James McKay, Pat Scott
The radiatively-induced splitting of masses in electroweak multiplets is relevant for both collider phenomenology and dark matter. Precision two-loop corrections of (M…
Global fits of the scalar singlet model using GAMBIT
James McKay
The extension of the standard model (SM) by a Higgs portal scalar field is one the simplest dark matter theories. We present here the first results for a global fit to this model u…
Pitfalls of iterative pole mass calculation in electroweak multiplets
James McKay, Pat Scott, Peter Athron
The radiatively-induced mass splitting between components of an electroweak multiplet is typically of order 100 MeV. This is sufficient to endow the charged components with macrosc…
Comparison of statistical sampling methods with ScannerBit, the GAMBIT scanning module
The GAMBIT Scanner Workgroup, :, Gregory D. Martinez +6
We introduce ScannerBit, the statistics and sampling module of the public, open-source global fitting framework GAMBIT. ScannerBit provides a standardised interface to different sa…
SpecBit, DecayBit and PrecisionBit: GAMBIT modules for computing mass spectra, particle decay rates and precision observables
The GAMBIT Models Workgroup, :, Peter Athron +12
We present the GAMBIT modules SpecBit, DecayBit and PrecisionBit. Together they provide a new framework for linking publicly available spectrum generators, decay codes and other pr…
Status of the scalar singlet dark matter model
The GAMBIT Collaboration, Peter Athron, Csaba Balázs +24
One of the simplest viable models for dark matter is an additional neutral scalar, stabilised by a symmetry. Using the GAMBIT package and combining results from four…
GAMBIT: The Global and Modular Beyond-the-Standard-Model Inference Tool
The GAMBIT Collaboration, Peter Athron, Csaba Balazs +29
We describe the open-source global fitting package GAMBIT: the Global And Modular Beyond-the-Standard-Model Inference Tool. GAMBIT combines extensive calculations of observables an…
Defining the frame of minimum nonlinear Hubble expansion variation
James H. McKay, David L. Wiltshire
We characterize a cosmic rest frame in which the monopole variation of the spherically averaged nonlinear Hubble expansion is most uniform, under arbitrary local Lorentz boosts of…
