B − L if we assume the seesaw mechanism. In the case of a gauged , the gauge bosons associated with this symmetry are commonly called X and Y bosons. The anomalies that would break baryon number conservation and lepton number conservation individually cancel in such a way that is always conserved. One hypothetical example is proton decay where a proton (; ) would decay into a pion (, ) and positron (; ). Weak hypercharge Y is related to via where X is the U(1) symmetry Grand Unified Theory-associated conserved quantum number. B − L In high energy physics, B" − "L
