Two-photon laser spectroscopy of antiprotonic helium and the antiproton-to-electron mass ratio
Physical laws are believed to be invariant under the combined transformations of charge, parity and time reversal (CPT symmetry). This implies that an antimatter particle has exactly the same mass and absolute value of charge as its particle counterpart. Metastable antiprotonic helium ($\bar{p}He^+$...
