While revisiting Klein-Gordon relativistic quantum equation for spin-0 particles (bosons), we predict that the Planck constant h reverses its sign for negative energies. We formulated a universal symmetry rule, whereby all the parameters that couple particles to external fields reverse their sign along with h at a particle↔antiparticle transformation.
This in particular implies anti-gravitation between matter and antimatter. It also brings about unexpected cosmological consequences by suggesting for mation of "checkered universe" made by separated matter-antimatter cells-subuniverses. Our results suggest that the h-conjugation principle and related invariance may replace CPT-invariance in general relativistic quantum mechanics.
