From the passage provided, extract the names of elementary particles and arrange them in alphabetical order

Context: In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. Particles currently thought to be elementary include electrons, the fundamental fermions, as well as the fundamental bosons, which generally are force particles that mediate interactions among fermions.A particle containing two or more elementary particles is a composite particle.
