Yeap. There is no need to change the sign of the gravitational mass of antimatter.

CPT symmetry ensures the same self-attractive gravitational behavior for both matter and antimatter. But, if we transform only one of the two components, either the field or the particle (represented by the remaining three elements), we get a change of sign that converts the original gravitational attraction into repulsion, so that matter and antimatter repel each other.

Antimatter is still attracted to it's self though.

Maybe they play a part in it too?

Not just kaons, but in b-mesons and neutrino osculations as well...

also it might explain matter/antimatter asymmetry
