T Violation in K-Meson Decays

Abstract

This presentation at the conference "50 years of CP violation", 10 - 11 July 2014, held at Queen Mary University of London covers an introduction to time reversal and motion reversal, the phenomenology of K0-K0bar transitions, unitarity relations, the first observation of T violation in 1970, later results from Bell-Steinberger unitarity analyses, searches for T violation in K0 to pi ell nu decay amplitudes and in the transverse muon polarisation of K to pi mu nu decays, direct observation of T violation by motion reversal in K0-K0bar transitions, and "direct T violation" in K0 to pi pi, I=2 decays (epsilon-prime).

Comments: 13 pages, 7 figures, to appear in the proceedings of the conference "50 years of CP violation", 10 - 11 July 2014, held at Queen Mary University of London, UK
