Query: Kaon CP violation and neutron EDM in the minimal left-right symmetric
  model   Within the minimal Left-Right (LR) symmetric model we revisit the predictions
for the kaon CP violating observables $\varepsilon$ and $\varepsilon'$ in
correlation with the neutron electric dipole moment. We perform a complete
study of the cross constraints on the model parameters, phases and the
$M_{W_R}$ scale, considering the two cases of extended parity or charge
conjugation as LR discrete symmetries, together with the possible presence of a
Peccei-Quinn symmetry. We discuss in particular two scenarios: whether the
Standard Model saturates the experimental value of $\varepsilon'/\varepsilon$
or whether new physics is needed, still an open issue after the recent lattice
results on the QCD penguin matrix elements. Within the first scenario, we find
no constraints on the LR scale in the charge-conjugation case while in the
parity case we show that $M_{W_R}$ can be as low as 13 TeV. On the other side,
the request that new physics contributes dominantly to $\varepsilon'$ implies
strong correlations among the model parameters, with an upper bound of
$M_{W_R}< 8-100$ TeV depending on $\tan\beta$ in the case of charge conjugation
and a range of $M_{W_R}\simeq 7-45$ TeV in the parity setup. Both scenarios may
be probed directly at future colliders and only indirectly at the LHC.
