Collider constraints on tuning in composite Higgs models
Barnard, James; White, Martin (2015)
Projects: ARC | Future Fellowships - Grant ID: FT140100244 (FT140100244)Two potential sources of tuning exist in composite Higgs models: one comes from keeping the Higgs VEV below the compositeness scale and one comes from keeping the Higgs light after constraints on the top partner masses are applied. We construct a measure that determines whether these tunings are independent or not and combines them appropriately. We perform a comprehensive scan of the parameter space for three explicit models and report the minimum tuning values compatible with existing colli...Constraining fine tuning in Composite Higgs Models with partially composite leptons
Barnard, James; Murnane, Daniel; White, Martin; Williams, Anthony G. (2017)
Projects: ARC | Future Fellowships - Grant ID: FT140100244 (FT140100244)Minimal Composite Higgs Models (MCHM) have long provided a solution to the hierarchy problem of the Standard Model, yet suffer from various sources of fine tuning that are becoming increasingly problematic with the lack of new physics observations at the LHC. We develop a new fine tuning measure that accurately counts each contribution to fine tuning (single, double, triple, etc) that can occur in a theory with $n_p$ parameters, that must reproduce $n_o$ observables. We then use a novel scann...Gravitational wave, collider and dark matter signals from a scalar singlet electroweak baryogenesis
Beniwal, Ankit; Lewicki, Marek; Wells, James D.; White, Martin; Williams, Anthony G. (2017)
Projects: ARC | Future Fellowships - Grant ID: FT140100244 (FT140100244)We analyse a simple extension of the SM with just an additional scalar singlet coupled to the Higgs boson. We discuss the possible probes for electroweak baryogenesis in this model including collider searches, gravitational wave and direct dark matter detection signals. We show that a large portion of the model parameter space exists where the observation of gravitational waves would allow detection while the indirect collider searches would not.Status of the scalar singlet dark matter model

Using the GAMBIT package and combining results from four independent samplers, we present Bayesian and frequentist global fits of this model. We vary the singlet mass and coupling along with 13 nuisance parameters, including nuclear uncertainties relevant for direct detection, the local dark matter density, and selected quark masses and couplings. We include the dark ma...A global fit of the MSSM with GAMBIT

Our analysis significantly extends previous weak-scale, phenomenological MSSM fits, by adding more and newer experimental analyses, improving the accuracy and detail of theoretical predictions, including dominant uncertainties from the Standard Model, the Galactic dark matter halo and the quark content of the nucleon, and employing...GAMBIT: the global and modular beyond-the-standard-model inference tool
