Probing parity violating interactions beyond the Standard Model with molecular spectroscpy — •Konstantin Gaul — Helmholtz Institute Mainz, Staudingerweg 18, 55128 Mainz
Dark spin-1 bosons, such as dark photons or Z’ bosons, are particularly interesting dark matter (DM) candidates which are predicted by several theories that extend the Standard Model (SM). The Z’ boson could act as a possible link between visible matter and DM and would be a source for a violation of parity beyond the SM [1]. Studying such parity violating interactions over a broad range of boson masses M is challenging for common low-energy dark matter detection methods [2]. In contrast, experiments based on internal interactions of atoms or molecules are sensitive to long range interactions M→∞, as well as interactions at much shorter range on the scale of atomic sizes M103 eV/c2 and even down to nuclear sizes M∼108 eV/c2 and could, therefore, provide a versatile platform to study parity violating dark matter [2]. An abundance of close-lying states of opposite parity, which can enhance parity violating interactions by several orders of magnitude, renders polar linear molecules and chiral molecules particularly interesting for this purpose [3,4]. In this contribution the sensitivity of current molecular experiments to Z’ bosons and prospects of future experiments will be discussed from a theory perspective.
