Computing Tools for Effective Field Theories
Jason Aebischer, Matteo Fael, Javier Fuentes-Martín +30
In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics. In…
Constraints on anomalous dimensions from the positivity of the S-matrix
Mikael Chala
We show that the analyticity and crossing symmetry of the S-matrix, together with the optical theorem, impose restrictions on the renormalisation group evolution of dimension-eight…
Neutrino masses in the Standard Model effective field theory
Mikael Chala, Arsenii Titov
We compute the leading-logarithmic correction to the neutrino mass matrix in the Standard Model effective field theory (SMEFT) to dimension seven. In the limit of negligible lepton…
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…
