Description
The existence of CP violating terms in the trace of the
energy-momentum tensor in chiral theories coupled to gravity has no
answer yet. Consequently, the neutrino could carry a source of CP or
unitarity violation in its trace anomaly within the Standard Model. This
talk aims to clarify the situation by presenting exclusive
non-perturbative computations of the trace anomaly in curved spacetime,
which should be helpful in settling the controversy.
