Description
Being purely leptonic, i.e. made of constituents which have (to the best of our knowledge) no internal structure, Muonium (M) is an excellent candidate to probe b-QED. I will present our recent measurement of the n=2 M Lamb Shift of 1047.2(2.5) MHz, which comprises an order of magnitud improvement upon the last determinations and matches with theory within one sigma. This allows us to set limits on Lorentz and CPT violation in
the muonic sector, as well as on new physics coupled to muons and electrons which could provide an explanation of the muon g-2 anomaly. I will discuss the future prospects of such a measurement and the current status of the 1S-2S experiment.
