Word definitions in Wikipedia
Corresponding to most kinds of particles , there is an associated antimatter antiparticle with the same mass and opposite charge (including electric charge ). For example, the antiparticle of the electron is the positively charged positron , which is produced ...

Usage examples of antiparticle.
My own belief is that eventually, something like this will change particles into antiparticles and vice versa.
The old murderers learned to tap the zero point field, that all-pervasive sea of energy where particles and antiparticles engage in a continuous dance of creation and annihilation.
Scientists would soon find themselves adrift in a bewildering realm of particles and antiparticles, where things pop in and out of existence in spans of time that make nanoseconds look plodding and uneventful, where everything is strange.
The cube worlds were antiparticles, moving back through time to initiate their own creation.
Holes move, just as moholes seem to move, just as a discrete particle can separate itself from a continuously dense array, leaving behind its antiparticle or hole.
The values for particle and antiparticle cancel, and their bound energy is released in mutual annihilation.
When a particle collides with its antiparticle, they annihilate, leaving only energy.
It comprises time reversal T combined with interchange of antiparticles and particles, called charge conjugation C, and a mirror-reflection or inversion of space, called parity reversal P.
We have evidence from cosmic rays that the same is true for all the matter in our galaxy: there are no antiprotons or antineutrons apart from a small number that are produced as particle/ antiparticle pairs in high-energy collisions.
Nevertheless, all the exotic variations created could be accounted for by the same eight ground-state quarks and leptons, plus their respective antiparticles, together with the field quanta through which they interacted.
It followed that “antitweedles” didn’t necessarily give an antiparticle, and tweedles didn’t always make a particle.
The explanation of how black holes can emit particles and radiation (given in Chapter 7) was that one member of a virtual particle/ antiparticle pair (say, the antiparticle) might fall into the black hole, leaving the other member without a partner with which to annihilate.
It is therefore possible, if a black hole is present, for the virtual particle with negative energy to fall into the black hole and become a real particle or antiparticle.
