Ultracold trapped molecules for tests of fundamental symmetries — •Joost van den Berg, Sreekanth Mathavan, Corine Meinema, Artem Zapara, Klaus Jungmann, and Steven Hoekstra — Van Swinderen Institute, University of Groningen, The Netherlands

Effects such as parity violation and electron electric dipole moments can be greatly enhanced in diatomic molecules because of their energy level structure. Therefore ultracold molecules can be used for precision tests of fundamental physics to look for physics beyond the Standard Model. Recent developments make it possible to create and trap cold samples of molecules. Trapped molecules offer a coherent measurement time which can be two orders of magnitude larger than a molecular beam experiment. We aim for a measurement of molecular parity violation with trapped, laser cooled molecules and we will present the tools which we are developing in our lab in order to reach this goal. These tools can be useful for the broad field of molecular experiments looking for physics beyond the standard model, such as permanent electric dipole moments or dark Z-bosons.
