Picture Of CP Violation Research Articles

CP-violating phases in the CKM matrix in orbifold compactifications

The picture of CP-violation in orbifold compactifications in which the T-modulus is at a complex fixed point of the modular group is studied. CP-violation in the neutral kaon system and in the neutron electric dipole moment are both discussed. The situation where the T-modulus takes complex values on the unit circle which are not at a fixed point is also discussed.

CP violation 1984: The KM model confronts experiment

Using recent experimental data involving the b, t quarks and the new measurement of η +−/ η oo we show that the KM picture of CP violation is barely compatible with these results. Slight improvements in any of these limits could require abandonement of the KM picture as the sole source of CP nonconservation, and some of the resultant required “new physics” is discussed.
