New physics and evidence for a complex CKM Original Research Article

We carefully analyse the present experimental evidence for a complex CKM matrix, even allowing for new physics contributions to image, image, image, image, and the image piece of image and image. We emphasize the crucial rôle played by the angle γ in both providing irrefutable evidence for a complex CKM matrix and placing constraints on the size of NP contributions. It is shown that even if one allows for new physics a real CKM matrix is excluded at a 99.92% C.L., and the probability for the phase γ to be in the interval image is 99.7%.
