Abstract
The LHC evidence for the Higgs particle strongly suggests that fundamental scalar fields are among nature's building blocks, and the most direct way to infer their presence is (arguably) to search for spacetime variations of nature's fundamental constants. As any Grand Unified Theory predicts a specific relation between variations of the fine-structure constant and the proton-to-electron mass ratio, simultaneous measurements of both provide key consistency tests. One sort of these consistency tests may be given, for instance, by atomic clocks. In our work we used the latest atomic clock measurements to improve the constraints on the variation of fundamental couplings.
