Laser-modified Angular Distribution of Muon Decay

TL;DR

This paper theoretically demonstrates that a strong laser field can significantly alter the angular distribution of muon decay, potentially revealing internal structures of the muon contrary to the standard model.

Contribution

It introduces a new theoretical approach to modify muon decay angular distribution using intense laser fields, suggesting possible internal muon structures.

Findings

Laser fields can dramatically change muon decay angular distribution

Muons may possess internal structures as indicated by the results

All electronic multiphoton processes are considered in the analysis

Abstract

We show theoretically that the angular distribution of decay rate of muon can be changed dramatically by embedding the decaying muon in a strong linearly polarized laser field. Evaluating the S-matrix elements taking all electronic multiphoton processes into account. The results suggest the muon may have internal structures instead structureless as in the standard model.
