Atomic probes of new physics
Year: 2016
Type: preprint
Abstract: Precise isotope shift spectroscopy in various atomic systems can provide a sensitive tool to constrain new physics, in particular new physics that couples to electrons and neutrons [1]. We present an analysis for estimating the reach of such measurements in the framework of effective field theory and various benchmark models for SM extensions: color neutral vector resonances, leptoquarks and the $750\,\textrm{GeV}$ scalar diphoton resonance. We also provide a comparison with the reach of the LHC, $e^+e^-$ colliders and $g-2$ of the electron. Isotope shift spectroscopy can compete and possibly even improve the sensitivity to probe a broad variety of Standard Model extensions.
