Description
For a general Hb→Hcτν− decay we analyze the role of the τ polarization vector in the context of LFU violation studies. We use a general phenomenological that includes several new physics terms. We show that both in the laboratory frame and in the center of mass, a P component is only possible for complex Wilson coefficients. We make specific evaluations of the polarization vector components for some decays, specially for Λb→Λc transitions.
