Abstract

We give a unitary description of T-odd effects in various sectors of atomic, nuclear and particle physics, like elastic scattering, deep inelastic processes and weak decays. This we get thanks to a particular transformation, which leads us to defining two T-odd observables. This approach allows to revise in quite a natural way various azimuthal asymmetries and normal polarizations already predicted or even observed in deep inelastic processes and in weak decays. In the latter case, useful suggestions for phenomenological analyses and an interesting result for normal and transverse polarization are derived.
