Quantum Field Theory

摘要: This book develops quantum field theory starting from its foundation in mechanics. Quantum is the basic of elementary particle physics. In recent years, many techniques have been developed which extend and clarify this theory. incorporates these modern methods, giving a thoroughly pedagogic account starts first principles. The path integral formulation introduced right at beginning. method dimensional continuation employed to regulate renormalize facilitates introduction concepts renormalization group an early stage. notion spontaneous symmetry breakdown also on by example superfluid helium. Topics electrodynamics are described analog chromodynamics. Some novel employed, such as use compute Lamb shift. Many problems included.
