Dissipative contributions to epsilon'/epsilon

TL;DR

This paper investigates how non-standard dissipative effects, modeled via quantum dynamical semigroups with six new parameters, influence the measurement of epsilon'/epsilon in neutral kaon decays.

Contribution

It introduces a framework incorporating six new phenomenological constants to describe dissipative effects in neutral kaon evolution and analyzes their impact on epsilon'/epsilon determination.

Findings

Non-standard dissipative terms can significantly alter epsilon'/epsilon measurements.

The framework allows for new phenomenological constants to be constrained by experiments.

Dissipative effects may lead to observable deviations from standard predictions.

Abstract

The time evolution and decay of the neutral kaon system can be described using quantum dynamical semigroups. Non-standard terms appear in the expression of relevant observables; they can be parametrized in terms of six, new phenomenological constants. We discuss how the presence of these constants affects the determination of the parameter epsilon'/epsilon.
