Flavorful Lepton-Number-Violating SMEFT: Loop Mixing, and Rare Meson Decays
Lukáš Gráf, Chandan Hati, Ana Martín-Galán +1
We investigate how one-loop operator mixing reshapes the flavor sensitivity of lepton-number-violating dimension-7 SMEFT interactions. Using both bottom-up and top-down EFT approac…
Displaced Signals from Long-lived Particles in Neutrinoless Double Beta Decay
Patrick D. Bolton, Noor-Inès Boudjema, Frank F. Deppisch +2
Much of the literature on neutrinoless double beta () decay with light new-physics mediators focuses on invisible missing energy. We investigate the scenario in which a massi…
Echoes of Nucleon Decay from Long-Lived Particles
Patrick Adolf, Chandan Hati, Martin Hirsch +1
Nucleon decay searches provide uniquely sensitive probes of baryon number violation and physics beyond the Standard Model. We propose a new class of nucleon decay observables invol…
Cartography of LNV dim-9 SMEFT: Implications for Radiative Neutrino Masses and
Fabian Esser, Lukáš Gráf, Chandan Hati
We perform a systematic study of lepton-number-violating (LNV) dimension-9 operators in the Standard Model Effective Field Theory (SMEFT) that can mediate neutrinoless double beta…
Keeping It Renormalizable: Minimal Baryogenesis induced Asymmetric Dark Matter
Miguel Escudero, Thomas Hambye, Chandan Hati
Many asymmetric dark matter scenarios have been proposed to date. Among them, perhaps the most motivated ones are those in which the dark matter asymmetry is induced from the baryo…
Long-Lived HNLs via ALP Portal at the LHC
Rebeca Beltrán, Chandan Hati, Martin Hirsch +1
Heavy neutral leptons (HNLs) and axion-like particles (ALPs) are both considered well-motivated candidates for beyond the standard model (BSM) physics. If ALPs with sizable couplin…
