The role of moduli stabilization in predictions for CP violation is examined in the context of four-dimensional effective supergravity models obtained from the weakly coupled heterotic string. We point out that while stabilization of compactification moduli has been studied extensively, the determination of background values for other scalars by dynamical means has not been subjected to the same degree of scrutiny. These other complex scalars are important potential sources of CP violation and we show in a simple model how their background values (including complex phases) may be determined from the minimization of the supergravity scalar potential, subject to the constraint of vanishing cosmological constant.

It is demonstrated that for a determination of the mass difference of the [Formula: see text] and [Formula: see text] mesons an explicit theoretical formula to be derived by an assumption of the CP-conservation has been used by CPLEAR Collaboration in a fitting of the time-dependent CPLEAR data on ASYMMETRY. So, in such procedure the mass difference [Formula: see text] of the [Formula: see text] and [Formula: see text] mesons has been found and in no case [Formula: see text] one as in this case the CP-violation has to be considered.

The physics program of LHCb concerns the study of CP violation in the B system, including more precise determination of the CKM matrix parameters and in particular the determination of φs The search for new physics which could manifest itself indirectly will be a high priority. The main advantages of LHCb over the B factories are the access to the Bs system and very large B production rates. In addition, LHCb is a dedicated B physics experiment with excellent vertexing and particle identification capabilities. It is currently setting up its detector in its allocated LHC interaction region and is foreseen to be ready for data taking in November 2007 for the pilot run.

We study the possibility of determining the octant of the neutrino mixing angle 23, that is, whether 23 > 45 or 23 < 45, in long baseline neutrino experiments. Here we numerically derived the sensitivity limits within which these experiments can determine, by measuring the probability of the ! e transitions, the octant of 23 with a 5 certainty. The interference of the CP violation angle with these limits, as well as the effects of the baseline length and the run-time ratio of neutrino and antineutrino modes of the beam have been analyzed.
