We calculate total and differential cross sections for the pair production, at the Large Hadron Collider, of exotic leptons that could emerge from models with vector-like leptons and in Type-III seesaw scenarios. Our predictions include next-to-leading-order QCD corrections, and we subsequently match them with either parton showers, or threshold resummation at the next-to-next-to-leading...
The separation of scales in effective field theories is essential for studying the low-energy phenomenology of BSM models. An effective theory, containing only light degrees of freedom, can be obtained from an underlying UV theory by integrating out heavy states using path integral techniques, ensuring that both theories describe the same low-energy dynamics. It is important to perform this...
We present an updated global SMEFT analysis in the Top sector using the SFitter framework which focuses on a comprehensive treatment of uncertainties. We make use of a newly implemented marginalization procedure which allows for comparisons between profiling and marginalization methods. In addition, two top measurements included in the fit are updated using likelihoods made publicly available...
Measuring the Higgs boson couplings with an increasing precision is an indirect probe of new physics scenarios. In this talk, I will discuss how observing loop-induced deviations to hWW and hZZ couplings via new vectorlike leptons close to the weak scale can be used to deduce an upper bound on the mass scale of new bosons. This is an interesting example where observing a deviation to the...
The axion couplings and their relation to quantum anomalies are discussed.
I comment on a puzzling non-decoupling effect and its consequences.
In this talk I will review the physics case of a high energy muon collider for the exploration of new physics with particular focus on Higgs boson physics, top quark physics and dark matter. I will discuss the role of a high energy muon collider in the landscape of future experiment to probe new physics in the next decades.
