CP Violation: The Past as Prologue

TL;DR

This paper reviews the current state of CP violation measurements in K and B meson systems, emphasizing how future measurements could challenge existing theories and open new research frontiers.

Contribution

It highlights the importance of measuring CP violation parameters in B systems to test and potentially refute Superweak-like theories.

Findings

Current measurements of  and ' in K system and sin2eta in B system.

Future measurements could definitively rule out Superweak-like theories.

Discussion of upcoming research directions in CP violation.

Abstract

CP violation is now measured by three numbers: \epsilon and {\epsilon{^{\prime} for the K^{0} system and sin2\beta for B^{0}. A future measurement of the analogue of {\epsilon{^{\prime} for the B system would end any possibility of a Superweaklike Theory. Future frontiers in CP violation are briefly discussed.
