Abstract
Within the Standard Model Effective Field Theory framework, with operators up to dimension 6, we perform a model-independent analysis of the lepton-flavour-violating processes involving tau leptons. Namely, we study hadronic tau decays and $\ell$-$\tau$ conversion in nuclei, with $\ell= e, \mu$. Based on available experimental limits, we establish constraints on the Wilson coefficients of the operators contributing to these processes. The translation of these constraints into the most general leptoquark framework is also considered. Our work paves the way to extract the related information from Belle II and foreseen future experiments.

Report
A model-independent analysis of lepton flavor violation in hadronic tau decays and lepton-tau conversion in nuclei are studied within the Standard Model Effective Field Theory framework, with operators up to dimension 6. Based on available experimental limits, constraints on Wilson coefficients are placed. The translation of these constraints into the most general leptoquark framework is also considered. The framework can be used to extract related information from data collected by the Belle II and other furture experiments.
