Colloquium

Searching for physics beyond the Standard Model with high-precision spectroscopy?

Colloquium given by Cedric Delaunay

Abstract: 

The Standard Model (SM) successfully describes the fundamental interactions of elementary particles up to TeV energies. Nonetheless, there is New Physics (NP) beyond the SM, and the energy scale at which it becomes manifest is unknown. The common belief is that NP phenomena arise only at high energies, above the TeV scale. However, there are reasons to think that NP particles, which interact very weakly with the known ones, could be hiding at (much) lower energies. Ultra-high precision measurements in atomic and molecular spectroscopy offer an interesting set of probes for such scenarios, complementing the efforts invested at high-energy colliders. In this presentation, we will explore two different approaches based on hydrogen and atomic clock spectroscopy.
