Strong and Weak Interactions: Present Problems focuses on the reactions, transformations, and processes involved in strong and weak interaction, including baryonic, mesonic, and strange and non-strange resonances.
The selection first offers information on unitary symmetry and hadron and lepton internal symmetries. Topics include internal symmetry for leptons, algebra of the hadron vector current, leptons and hadrons, and the search for higher symmetries. The text then elaborates on algebras and weak interactions and relativistic quark model as representation of algebra.
The book takes a look at Regge poles in high-energy scattering and models of strong interactions. Discussions focus on electromagnetic properties, relations among strong vertices, medium-strong mass splittings, moving poles, high-energy kinematics, and Sommerfeld-Watson transformation. The text also ponders on meson resonances, phenomenology of resonances and particle supermultiplets, and meson photoproduction near threshold and commutation algebra.
The selection is highly recommended for readers interested in strong and weak interactions.
