Testing varying coupling constants through multi-Higgs production at the LHC
Ulf Danielsson, Rikard Enberg, Gunnar Ingelman +3
We propose the One Scalar Theory (1ST), a minimalist framework where a single real singlet scalar field mediates the dynamical generation of the Higgs self-coupling and the top Yuk…
A Catalog of First-Order Electroweak Phase Transitions in the Standard Model Effective Field Theory
Eliel Camargo-Molina, Rikard Enberg, Johan Löfgren
We use modern dimensionally-reduced effective field theory methods, with careful attention to scale hierarchies, to analyze and catalog the types of first-order electroweak phase t…
Constraints on the boson from IceCube searches for non-standard interactions of neutrinos
Rikard Enberg, YaÅar Hiçyılmaz, Stefano Moretti +2
We explain the ATOMKI anomaly with a very light state that features non-anomalous and non-flavour-universal vector and axial-vector couplings to all leptons. This comes f…
Generating particle physics Lagrangians with transformers
Yong Sheng Koay, Rikard Enberg, Stefano Moretti +1
In physics, Lagrangians provide a systematic way to describe laws governing physical systems. In the context of particle physics, they encode the interactions and behavior of the f…
Energy-dependent flavour ratios in neutrino telescopes from charm
Atri Bhattacharya, Rikard Enberg, Mary Hall Reno +1
The origin of the observed diffuse neutrino flux is not yet known. Studies of the relative flavour content of the neutrino flux detected at Earth can give information on the produc…
Vector-like quarks: status and new directions at the LHC
Avik Banerjee, Elin Bergeaas Kuutmann, Venugopal Ellajosyula +3
Experimental searches for vector-like quarks have until now only considered their decays into Standard Model particles. However, various new physics scenarios predict additional sc…
