The simplest ones involve two vertices, and on them antiparticles are represented as moving anti-temporally.
The simplest ones involve two vertices, and on them antiparticles are represented as moving anti-temporally. One axis is chosen to represent space, while the other represents time. Straight lines are used to depict particles with half-integral values like fermions, while wavy lines are used for bosons. FTP identify these visualized graphic analogues of mathematical expressions describing the behavior of interacting particles, named for an American physicist.
