Searching for New Physics by means of Relative Phases and Moduli of Decay Amplitudes

TL;DR

This paper discusses tests involving decay amplitudes' phases and moduli to detect potential signals of new physics beyond the Standard Model.

Contribution

It introduces specific tests based on decay amplitude measurements that are highly sensitive to new physics signals.

Findings

Certain tests can effectively reveal deviations from the Standard Model.

Some decay amplitude measurements are particularly sensitive to new physics.

The proposed methods could guide future experimental searches.

Abstract

We illustrate some tests which may shed light on physics beyond the Standard Model. Some of them are especially sensitive to possible signals of new physics.
