  • If every fermion (or boson) came with another particle, the same in every respect except in that it was a boson (or fermion), then the energies would cancel. —  AnalogSFF,July-August2008
  • On the other hand, the four-fermion processes like quark-antiquark scattering include also the exchanges of heavy Kaluza-Klein and winding states, whose details depend on the form of internal geometry. —  CiteULike: Everyone's library
  • Each fermion will naturally pair up with one that is spinning in the opposite direction, so that the two spins cancel each other out. —  PhysOrg.com - latest science and technology news stories
