Beta decays in the LHC era: from ultracold neutrons to colliders

TL;DR

This paper reviews the potential of semileptonic beta decay experiments to discover new physics and compares their sensitivity with LHC collider searches using an Effective Field Theory framework.

Contribution

It introduces a model-independent method to compare low-energy beta decay experiments with high-energy LHC searches for new particles.

Findings

Effective Field Theory enables direct comparison between low-energy and collider experiments.

Beta decay experiments can probe new physics complementary to LHC searches.

The approach facilitates understanding of new physics reach across different energy scales.

Abstract

In this talk I review the New Physics reach of semileptonic beta decay experiments, and their interplay with LHC searches. Assuming the new particles are heavy enough we can use an Effective Field Theory approach to analyze the LHC searches, what allows us to perform a direct and model-independent comparison with low-energy experiments.
