Description
The permanent electric dipole moment (EDM) of a fundamental particle is a CP violating property, and can be used as a sensitive probe for physics beyond the Standard Model (BSM). The electron leaves a greatly enhanced EDM signature when bound to a heavy polar molecule. This has allowed molecular precision measurements to explore well into the parameter space of BSM theories. A next generation of electron EDM experiments will be performed using trapped polyatomic molecules, which offer longer coherence times and reduced systematic effects [1]. We have investigated the main challenges and requirements needed to realise a competitive measurement using trapped BaOH molecules [2,3]. In this talk I will outline our approach, which is capable of testing the Standard Model reaching for PeV energy scales.
