the mirror fails

LITParity, inverting space (x → −x), was assumed to be a symmetry of all physics until Lee and Yang (1956) pointed out that it had never been tested for the weak force. Chien-Shiung Wu’s team aligned cobalt-60 nuclear spins at very low temperature (Phys. Rev. 105, 1413, 1957), and the beta electrons came out preferentially opposite the spin. A mirror flips spin but not the direction of motion, so the mirrored experiment would show the opposite asymmetry: nature is not mirror-symmetric. CP is also violated (kaons, 1964); CPT is believed exact.

MODELEmission ∝ 1 + A·cos θ relative to the spin, with A on the slider (the measured asymmetry was diluted by incomplete polarisation). The right panel is the mirror world.
