Dynamical Symmetry Breaking In Quantum Field Theories

Discusses differential aspects of dynamical symmetry breaking (DSB) in quantum field theory. Applications of DSB to such theories as chromo-dynamics and electroweak interactions are considered, and problems intimately connected with DSB (anomalies, effective lagrangian approach) are examined.

---

The phenomenon of dynamical symmetry breaking (DSB) in quantum field theory is discussed in a detailed and comprehensive way. The deep connection between this phenomenon in condensed matter physics and particle physics is emphasized. The realizations of DSB in such realistic theories as quantum chromodynamics and electroweak theory are considered. Issues intimately connected with DSB such as critical phenomenona and effective lagrangian approach are also discussed.
