68. Relating Charged and Neutral Lepton Flavor Violation with Effective Field Theory

Many experiments have been conducted to search for charged lepton flavor violation (CLFV) and have yielded very strong constraints. At the same time, there has been much interest in neutrino nonstandard interactions (NSI), which could also in general be flavor-violating. However, the direct constraints on NSI are typically rather weak due to the present limitations of neutrino experiments. ...

The observation of lepton number violation (LNV) would be clear evidence for physics beyond the Standard Model, and non-zero neutrino masses particularly motivate a study of processes that violate lepton number by two units, like e.g. neutrinoless double beta decay.
In the Standard Model Effective Field Theory (SMEFT), $\Delta L =2$ operators appear at dimension-5 and higher odd...

14. From DUNE Sensitivities to UV Models: Implications of Flavor Constraints

Future neutrino experiments, in particular DUNE, are expected to probe new physics through their sensitivity to non-standard neutrino interactions (NSIs), i.e. LEFT/WEFT dimension-six Wilson coefficients. We investigate whether such effects can arise from realistic ultraviolet (UV) models. To this purpose we develop a computational pipeline that connects UV scenarios to phenomenological...
