Neutrino oscillations physics is entered in the precision era. In this context accelerator-based neutrino experiments need a reduction of systematic errors to the level of a few percent. Today one of the most important sources of systematic…
We argue that CP--violation effects below a few tenths of a percent are probably undetectable at hadron and electron colliders. Thus only operators whose contributions interfere with tree--level Standard Model amplitudes are detectable. We…

CP violating asymmetries in both the production and the decays of $s$-channel neutral Higgs bosons at $\mu^+\mu^-$ colliders can be large. If the CP violation occurs in the muon-Higgs coupling, one observes a production asymmetry with…
