<b>Time-Reversal Violation in the Nucleon and Light Nuclei
</b><br>

<br>
A new generation of experiments is being planned with a significant
improvement in the sensitivity to electric dipole moments (EDMs) of
the nucleon and light nuclei. Possible signals in these measurements
would reflect time-reversal violation (TV) beyond that stemming from
the phase of the CKM matrix. Could we then infer the origin of TV at
the quark/gluon level?
<br>
<br>
I describe our on-going program to relate nucleon and light-nuclear TV
observables to various TV sources, such as the QCD theta term, quark
EDMs, quark and gluon color-EDMs, etc. We use the effective field
theory of QCD that is applicable to hadronic momenta of order of the
pion mass - a generalization of chiral perturbation theory - and can
handle one- and many-nucleon physics consistently. I argue that light
nuclei could offer the key to disentangle TV sources.
