There are also four antiparticles with opposite charges, made up of the corresponding antiquarks.
The antiparticle of the electron is the antielectron, which is nearly always called "positron" for historical reasons.
Instead of being states with no antiparticle, these are states that are already filled with a negative energy particle.
Although the and its antiparticle are usually produced via the strong force, they decay weakly.
The latter is seen in many processes in which both a particle and its antiparticle are created simultaneously, as in particle accelerators.
The remarkable notion of an antiparticle to each fermion particle e.g. the positron as antiparticle to the electron stems from his equation.
When a particle and antiparticle scatter, virtual particles can be exchanged in two qualitatively different ways.
The antiparticles are then led into a recombination trap to create antihydrogen.
