Studying CP Violation -- Chances for a New Alliance

High Energy Physics - Phenomenology 2017-08-23 v1

Abstract

The last three years have seen a phase transition in our knowledge about CP violation: (i) Direct CP violation has been established in KLππK_L \to \pi \pi. (ii) The first CP violation outside KLK_L decays has been observed in BdψKSB_d \to \psi K_S: <sin2ϕ1>=0.78±0.08<{\rm sin}2\phi_1 > = 0.78 \pm 0.08 in amazing agreement with the prediction from the CKM description. The latter is thus seen as a tested theory. This increase in knowledge is not matched by progress in understanding. Searches for further manifestations of CP and T violation are mandatory. It is argued that one can profit greatly from studying atoms, molecules and nuclei.
