Crossing symmetry — In quantum field theory, a branch of theoretical physics, crossing symmetry is a symmetry that relates S matrix elements. Interaction processes involving different kinds of particles can be obtained from each other by replacing incoming particles … Wikipedia

Symmetry breaking — in physics describes a phenomenon where (infinitesimally) small fluctuations acting on a system crossing a critical point decide a system s fate, by determining which branch of a bifurcation is taken. For an outside observer unaware of the… … Wikipedia
