Current and future constraints on heavy New Physics from weak dipole moments

Nejc Košnik, Zachary Polonsky, Aleks Smolkovič

We study the weak magnetic and electric dipole moments of the lepton as precision tests of the Standard Model (SM) and probes of heavy New Physics (NP). We present an updated S…

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…

CP-odd window into long distance dynamics in rare semileptonic decays

Jernej F. Kamenik, Nejc Košnik, Martín Novoa-Brunet

We consider the combined measurements of CP-averaged decay rates and direct CP asymmetries of and to probe (non-local)…

On a model with two scalar leptoquarks -- and

Damir Bečirević, Ilja Doršner, Svjetlana Fajfer +4

We discuss a model that can accommodate the -physics anomalies, based on combining two scalar leptoquarks, and , of mass , and that we p…

LFU and CP violation with

Nejc Košnik, Aleks Smolkovič

We introduce the CP violating scalar leptoquark to explain the measured values of the lepton universality ratios . We derive constraints on the CP-even and CP-od…

Optimized probes of -odd effects in the process at hadron colliders

Blaž Bortolato, Jernej F. Kamenik, Nejc Košnik +1

We use machine learning (ML) and non-ML techniques to study optimized -odd observables, directly and maximally sensitive to the -odd interaction…
