T.D. LEE AND C.N. YANG won in 1956 received the Nobel Prize in physics for radically questioning one of physics' basic tenets. They interpreted results of particle decay experiments at BNL's (Brookhaven National Laboratory) Cosmotron particle accelerator and discovered that the fundamental and supposedly absolute law of parity conservation had been violated. The results they studied concerned two particles, the tau and the theta, which had the same masses, lifetimes and scattering behaviors, but which decayed differently in experiments at the Cosmotron.
Because of this, the law of parity conservation required that these otherwise similar particles be considered different from one another. Lee and Yang suggested experiments that showed that the weak interaction of radioactive decay could indeed violate parity conservation. When the experiments were later successfully completed, the puzzle of the two particles was solved -- they could be the same.
