Most of the free parameters in the Standard Model (SM)—a quantum field theory which has
successfully elucidated the behaviors of strong, weak and electromagnetic interactions of all …

This chapter of the report of the “Flavor in the era of the LHC” Workshop discusses the
theoretical, phenomenological and experimental issues related to flavor phenomena in the …

The super τ-charm facility (STCF) is an electron–positron collider proposed by the Chinese
particle physics community. It is designed to operate in a center-of-mass energy range from …

We review the collider phenomenology of neutrino physics and the synergetic aspects at
energy, intensity and cosmic frontiers to test the new physics behind the neutrino mass …

We perform a thorough study of thermal leptogenesis adding finite temperature effects, RGE
corrections, scatterings involving gauge bosons and by properly avoiding overcounting on …

We present a search for lepton-flavor-violating τ decays into three leptons (electrons or
muons) using 782 fb− 1 of data collected with the Belle detector at the KEKB asymmetric …

The focus of this paper lies on the possible experimental tests of leptogenesis scenarios. We
consider both leptogenesis generated from oscillations, as well as leptogenesis from out-of …

A bstract Charged lepton flavor violation is forbidden in the Standard Model but possible in
several new physics scenarios. In many of these models, the radiative decays τ±→ ℓ±γ (ℓ …

Belle II is an experiment operating at the intensity frontier. Over the next decades, it will
record the decay of billions of bottom mesons, charm hadrons, and tau leptons produced in …

In this work the following lepton flavor violating τ and μ decays are studied: τ-→ μ-μ-μ+, τ-→
ee-e+, μ-→ ee-e+, τ-→ μ-γ, τ-→ e-γ, and μ-→ e-γ. We work in a supersymmetric scenario …
