Lyndon B. Johnson High School (Austin, Texas) Lyndon B. Johnson High School (Austin, Texas) Lyndon Baines Johnson (LBJ) Early College High School is a public high school in northeast Austin, Texas. At the time of its opening in 1974, LBJ was only the second high school in the U.S. (after the former Johnson City High School) to be named for the 36th President. In 1985, LBJ became the host of a new academic magnet program, the Science Academy of Austin, which drew students from all over the city. A second high school magnet program, the Liberal Arts Academy of Austin, was opened at Albert Sidney Johnston High
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
