QSNET, a network of clocks for measuring the stability of fundamental constants

TL;DR

QSNET is developing a UK network of advanced atomic and molecular clocks to precisely test for variations in fundamental constants, aiming to constrain theories beyond the Standard Model and dark matter models.

Contribution

The paper introduces the design and goals of QSNET, a novel network of highly sensitive clocks for fundamental physics tests.

Findings

Enhanced sensitivity to variations in fundamental constants

Potential to set new constraints on beyond Standard Model theories

Improved limits on dark matter interactions

Abstract

The QSNET consortium is building a UK network of next-generation atomic and molecular clocks that will achieve unprecedented sensitivity in testing variations of the fine structure constant, $\alpha$, and the electron-to-proton mass ratio, $\mu$. This in turn will provide more stringent constraints on a wide range of fundamental and phenomenological theories beyond the Standard Model and on dark matter models.
