We investigate collider signatures of standard model extensions featuring vector-like leptons and a flavorful scalar sector. Such a framework arises naturally within asymptotically safe model building, which tames the UV behavior of the standard model towards the Planck scale and beyond. We focus on values of Yukawa couplings and masses which allow to explain the present data on the muon and electron anomalous magnetic moments. Using a CMS search based on $$77.4 \, \text {fb}^{-1}$$ 77.4…
Searching for exotic production of Higgs boson + X to map out new physics
• Physics
Physical Review D
• 2021
We propose leveraging our proficiency for detecting Higgs resonances by using the Higgs as a tagging object for new heavy physics. In particular, we argue that searches for exotic Higgs production
Constraining low-scale flavor models with (g−2)μ and lepton flavor violation
• Physics
Physical Review D
• 2022
We present here two concrete examples of models where a sub-TeV scale breaking of their respective T13 and A5 flavor symmetries is able to account for the recently observed discrepancy in the muon
Asymptotic safety guaranteed for strongly coupled gauge theories
• Physics, Mathematics
Physical Review D
• 2022
We demonstrate that interacting ultraviolet fixed points in four dimensions exist at strong coupling, and away from large-N Veneziano limits. This is established exemplarily for semisimple

$$U(1)^\prime$$ U ( 1 ) ′ extensions of the standard model with generation-dependent couplings to quarks and leptons are investigated as an explanation of anomalies in rare B -decays, with an

NLO QCD corrections to full off-shell production of $t\bar{t}Z$ including leptonic decays

: Motivated by ongoing new physics searches in the top-quark sector at the Large Hadron Collider we report on the calculation of NLO QCD corrections to the Standard Model pp → t ¯ tZ + X process in
New leptons with exotic decays: collider limits and dark matter complementarity
• Physics
Journal of High Energy Physics
• 2022
Abstract We describe current and future hadron collider limits on new vector-like leptons with exotic decays. We consider the possibility that, besides standard decays, the new leptons can also
Systematically testing singlet models for (g − 2)μ

Journal of High Energy Physics
• 2022
Abstract We comprehensively study all viable new-physics scenarios that resolve the muon (g − 2)μ anomaly with only Standard Model singlet particles coupled to muons via renormalizable interactions.
Why should we search for vector-like leptons?
• Physics
• 2022
There are two strong arguments in favor of vector-like leptons and quarks: Flavor Democracy call for them, and E6 GUT predicts existence of iso-singlet quarks and iso-doublet leptons. Vector-like
