# The deformation parameter of the generalized uncertainty principle

## TL;DR

This paper reviews the generalized uncertainty principle (GUP), discusses experimental bounds on its deformation parameter, presents a theoretical estimate for this parameter, and highlights the potential for future experimental exploration.

## Contribution

It provides a comprehensive review of GUP predictions, summarizes current experimental bounds on the deformation parameter, and offers a theoretical estimate, emphasizing unexplored parameter regions.

## Key findings

- Experimental bounds on the deformation parameter $eta$
- A theoretical value for $eta$ is computed
- Large parameter space remains to be tested by future experiments

## Abstract

After a short introduction to the generalized uncertainty principle (GUP), we review some of the physical predictions of the GUP, and we focus in particular on the bounds that present experimental tests can put on the value of the deformation parameter $\beta$. We also describe a theoretical value computed for $\beta$, and comment on the vast parameter region still unexplored, and to be probed by future experiments.
