In this talk, I will focus on the Penning-trap experiment testing the charge-to-mass ratio of protons and antiprotons, and compare it with other experiments which also test matter-antimatter mass asymmetry. Using a simple yet powerful argument of mass decomposition of hadrons, I will show that bounds on quark-antiquark mass differences from kaon oscillations are way beyond the reach of Penning-trap experiments. Finally, I will lay out a roadmap to discuss possible reformulations of our understanding of the SM in the case of a discovery of CPT violation by these precision experiments.
