EFT Pathways to : Chiral Constructions and Phenomenology
Arnau Bas i Beneito, Ajdin Palavrić, Andrea Sainaghi
We develop a systematic effective field theory framework for studying interactions across energy scales. Using chiral symmetry, we construct the complete and non-redundant…
Implications of Flavor Symmetries for Baryon Number Violation
Arnau Bas i Beneito, Ajdin Palavrić, Andrea Sainaghi
In the Standard Model, baryon number is an accidental symmetry, whose violation would constitute unambiguous evidence of new physics, with proton decay providing its most prominent…
Expanding the Landscape of Exotic Muon Decays
Admir Greljo, Ajdin Palavrić, Mirsad Tunja +1
We chart new-physics models that produce exotic, high-multiplicity muon decays featuring prompt or displaced pairs and/or photons, with or without missing energy, such as…
UV origins of CP-violating leptonic Yukawa couplings
Nejc Košnik, Ajdin Palavrić, Aleks Smolkovič
Probing the CP nature of the Higgs Yukawa couplings is a promising avenue for unraveling new physics effects. In this work, we investigate the possible single- and two-field UV ori…
Leptonic Flavor from Modular : UV Mediators and SMEFT Realizations
Adrián Moreno-Sánchez, Ajdin Palavrić
The absence of direct evidence for new physics at current collider energies motivates the study of indirect effects within the framework of the Standard Model Effective Field Theor…
A Guide to Functional Methods Beyond One-Loop Order
Javier Fuentes-Martín, Adrián Moreno-Sánchez, Ajdin Palavrić +1
Functional methods can be applied to the quantum effective action to efficiently determine counterterms and matching conditions for effective field theories. We extend the toolbox…
