Running in the ALPs
Mikael Chala, Guilherme Guedes, Maria Ramos +1
The couplings of axion-like particles are probed by different experiments across a huge range of energy scales. Accordingly, a consistent analysis of the corresponding constraints…
The effective field theory of low scale see-saw at colliders
Anke Biekötter, Mikael Chala, Michael Spannowsky
We study the Standard Model effective field theory (SMEFT) extended with operators involving right-handed neutrinos, focussing on the regime where the right-handed neutrinos dec…
One-loop running of dimension-six Higgs-neutrino operators and implications of a large neutrino dipole moment
Mikael Chala, Arsenii Titov
We compute the one-loop running of the dimension-six CP-even Higgs operators in the Standard Model effective field theory involving the right-handed component of the would-be Dirac…
Effective field theory for vector-like leptons and its collider signals
Mikael Chala, Paweł Kozów, Maria Ramos +1
We argue that in models with several high scales; e.g. in composite Higgs models or in gauge extensions of the Standard Model (SM), vector-like leptons can be likely produced in a…
Novel flavour-changing neutral currents in the top quark sector
Nuno Castro, Mikael Chala, Ana Peixoto +1
We demonstrate that flavour-changing neutral currents in the top sector, mediated by leptophilic scalars at the electroweak scale, can easily arise in scenarios of new physics, and…
One-loop matching in the SMEFT extended with a sterile neutrino
Mikael Chala, Arsenii Titov
We study the phenomenology of the simplest renormalisable model that, at low energy, leads to the effective field theory of the Standard Model extended with right-handed neutrinos…
