Symmetries in Elementary Particle Physics focuses on the processes, methodologies, advancements, and reactions in elementary particle physics. The selection first offers information on symmetry principles in particle physics and vector and axial currents under first order symmetry breaking. Discussions focus on restrictions following from charge conjugation; non-renormalization theorem for the vector current octet; second class amplitudes for leptonic decays; and discrete symmetry operations. The text then takes a look at methods for assigning spin and parity to baryon resonances and general review of neutrino physics. The publication examines momentum spectrum of positrons from muon decay and the status of strong electromagnetic and weak interactions. Topics include basic physics, conservation laws, question of dynamics, and existential questions. The selection is a dependable reference for readers interested in the symmetries in elementary particle physics.
