# Can a spontaneous collapse in flavour oscillations be tested at KLOE?

## TL;DR

This paper explores whether spontaneous collapse models can be tested through high-energy flavour oscillations in neutral meson systems, proposing new interpretations and constraining collapse scenarios with experimental data.

## Contribution

It applies two specific collapse models to high-energy meson systems, offering a novel interpretation of decay rates and using experimental data to constrain collapse scenarios.

## Key findings

- Potential new interpretation of decay rates in standard formalism
- Experimental data constrains collapse models at high energies
- Highlights testability of collapse models in particle physics

## Abstract

Why do we never see a table in a superposition of here and there? This problem gets a solution by so called collapse models assuming the collapse as a genuinely physical process. Here we consider two specific collapse models and apply them to systems at high energies, i.e. flavour oscillating neutral meson systems. We find on one hand a potentially new interpretation of the decay rates introduced by hand in the standard formalism and on the other hand that these systems at high energies constrain by experimental data the possible collapse scenarios.
