31. The charge of an antiparticle equals that of the corresponding particle, but with opposite sign. 32. Within the advanced propagator ( as opposed to the retarded propagator ) is employed for antiparticles . 33. The strong charge of such a particle must be the same as that of its antiparticle . 34. Wheeler suggested that these backwards sections appeared as the antiparticle to the electron, the positron. 35. For example, the proton is denoted as, and its corresponding antiparticle is denoted as. 36. Why does the antiparticle get swallowed by the black hole in preference to the positive particle? 37. Theories of supersymmetry assume that for every known particle and antiparticle there is a corresponding supersymmetric particle. 38. Since then, the antiparticles of many other subatomic particles have been created in particle accelerator experiments. 39. Each baryon has a corresponding antiparticle ( antibaryon ) where quarks are replaced by their corresponding antiquarks. 40. These particles have lepton number + 1, while their antiparticles have lepton number " 1.
