The complex scalar singlet extension has three massive scalar states with interesting decay chains which will depend on the exact mass hierarchy of the system. We find maximum branching ratios for resonant double Standard Model-like Higgs production, resonant production of a Standard Model-like Higgs and a new scalar, and double resonant new scalar production. This is particularly interesting...
An important question for both phenomenologists and experimentalists is whether one can put limits on UV model parameters by matching the full theory onto the SMEFT. I will show that this is possible and explore the complementarity between SMEFT and model-specific approaches.
In particular, I will focus on an additional theory uncertainty arising from the matching at one-loop and discuss how...
Searches for new resonances in di-boson final states (VV and VH, where V = W, Z) and tri-boson (VVV) final states, with the CMS detector are presented. The results are based on the large dataset collected during Run 2 of the LHC at a centre-of-mass energy of 13 TeV. The analyses are optimised for high sensitivity over a large range in resonance mass. Jet substructure techniques are used to...
Many new physics models, e.g., compositeness, extra dimensions, extended Higgs sectors, supersymmetric theories, and dark sector extensions, are expected to manifest themselves in the final states with leptons and photons. This talk presents searches in CMS for new phenomena in the final states that include leptons and photons, focusing on the recent results obtained using the full Run-II...
This talk will cover research searches for extended HIggs sectors, including additional (charged) Higgs bosons and resonant HH production. The talk will also cover searches for BSM decays of the H(125) boson.
