On the direct evidence of time-reversal non-invariance in the $K^0-\bar K^0$ system

TL;DR

This paper reviews CP violation measurements in the $K^0-ar{K}^0$ system and argues that previous attempts to demonstrate T-violation from these data are flawed due to logical inconsistencies.

Contribution

It critically analyzes the evidence for T-violation in the $K^0-ar{K}^0$ system and highlights flaws in previous logical approaches.

Findings

CP violation parameters measured by CPLEAR are reviewed

Attempts to prove T-violation from semileptonic asymmetries are flawed

Logical inconsistencies undermine previous claims of T-violation evidence

Abstract

The measurements of the CP violation parameters by the CPLEAR experiment are reviewed. It is shown that attempts to prove T-violation from the semileptonic asymmetries are flawed by logical inconsistencies.
