Morphology

antimeson = meson (transparent) = anti + meson

The word is transparently formed with the productive prefix anti- meaning 'opposite' or 'counterpart of' added to meson.

Etymology

Antimeson is formed from anti- meaning 'opposite', as in antifreeze, and meson, from a Greek word for 'middle', like medium. So an antimeson is the 'opposite' of a meson, a particle partner that has opposite properties.
