We scrutinize the allowed parameter space of Little Higgs models with the concrete symmetry of T-parity by providing comprehensive LHC analyses of all relevant production channels of heavy vectors, top partners, heavy quarks and heavy leptons and all phenomenologically relevant decay channels. Constraints on the model will be derived from the signatures of jets and missing energy or leptons...
Four-top quarks processes are a relatively common signature of BSM theories, typically arising from the pair-production of strongly-coupled new physics fields. We present the recasting of a recent CMS search for four top quarks with same-sign lepton final state and its implementation in the MadAnalysis5 PAD framework. As an application, we derive new bounds on octet (pseudo-)scalar fields.
It is well known that the interpretation of experimental data depends on the theoretical model used for it. I will show a few examples of signals that are quite elusive and whose obvious interpretation, should any of them appear in data, could be completely wrong.
We present the current perspectives for SUSY, given the public Run 2 results, in a phenomenological Minimal Supersymmetric Standard Model scenario with eleven parameters (pMSSM11).
The study, from the MasterCode collaboration, includes the most...
A light singlino is a promising candidate for dark matter, and a light higgsino is natural in the parameter space of the NMSSM. We study constraints from recent searches for electroweakinos at the LHC on scenarios which are consistent with the dark matter relic density and bounds on dark matter direct detection cross sections. Benchmark points for future searches are proposed.
I will discuss first results of recasting early LHC Run-2 electroweak SUSY searches with GAMBIT, the Global and Modular Beyond-the-Standard Inference Tool. I will review the searches that have been recasted for this analysis and their specific implementations within the GAMBIT ColliderBit framework. Assuming a model with decoupled sfermions and gluinos, I will present combined constraints on...
