Abstract. In the minimal left-right symmetric model with spontaneous CP violation, there are only two intrinsic CP violating phases to account for all CP violation in both the quark and lepton sectors. In addition, the leftand right-handed Majorana mass terms for the neutrinos are proportional to each other due to the parity in the model. This is thus a very constrained framework, making the ex...

It is shown that in R-parity violating models of supersymmetry, the CP violation observed in the kaon system could arise purely from the R-parity violating scalar interactions (A-terms), with no CP violation in the CKM matrix. The direct CP violating parameter, ε, could be as large or larger than that expected in the Standard Model. CP violation in the B system however is expected to be negligi...

The phenomenon of CP violation is one of the most intriguing aspects of modern physics, with far-reaching implications for the microscopic world as well as for the macrocosmos. CP violation means that there is a fundamental difference between the interactions of matter and anti-matter, which in conjunction with the CPT theorem implies a microscopic violation of time-reversal invariance. CP viol...

With the time dependant CP asymmetry in Bd(t) → ψKS well measured, the most powerful method to search for direct CP violation in Bd decays is to analyze whether the CP asymmetry of other transitions like Bd(t) → π π, ηKS etc. can be described by a sin term taken from Bd(t) → ψKS and without a cos term. The failure of such a constrained fit would establish direct CP violation (even if no CP asym...

The Hyperon-CP-Violation working group at the p2000 Workshop met together with the Beta-Decay working group. After brie y introducing the physics, I summarize the workinggroup discussions relevent to CP violation. The working group sketched issues that need to be explored in designing a hyperon CP-violation experiment that might achieve 10 5 sensitivity for the CP asymmetry A , one order of mag...
