Query: CP Violation Tests of Alignment Models at LHCII   We analyse the low-energy phenomenology of alignment models both
model-independently and within supersymmetric (SUSY) scenarios focusing on
their CP violation tests at LHCII. Assuming that New Physics (NP) contributes
to K-Kbar and D-Dbar mixings only through non-renormalizable operators
involving SU(2)_L quark-doublets, we derive model-independent correlations
among CP violating observables of the two systems. Due to universality of CP
violation in Delta F=1 processes the bound on CP violation in Kaon mixing
generically leads to an upper bound on the size of CP violation in D mixing.
Interestingly, this bound is similar in magnitude to the current sensitivity
reached by the LHCb experiment which is starting now to probe the natural
predictions of alignment models. Within SUSY, we perform an exact analytical
computation of the full set of contributions for the D-Dbar mixing amplitude.
We point out that chargino effects are comparable and often dominant with
respect to gluino contributions making their inclusion in phenomenological
analyses essential. As a byproduct, we clarify the limit of applicability of
the commonly used mass insertion approximation in scenarios with
quasi-degenerate and split squarks.
