It is proved that the SU(2)-symmetric model of hadrodynamics can well be set up on the gaugeinvariance principle. The quantization of the model can readily be performed in the Lagrangian path-integral formalisms by using the Lagrangian undetermined multiplier method. Furthermore, it is shown that the quantum theory is invariant with respect to a kind of BRST-transformations. From the BRST-symme...

We show how an effective field theory of long distance QCD, describing a dual superconductor, can be expressed as an effective string theory of superconducting vortices. We use the semiclassical expansion of this effective string theory about a classical rotating string solution in any spacetime dimension D to obtain the semiclassical meson energy spectrum. We argue that the experimental data o...

Invariance under the combined transformations of CPT (in any order) is guaranteed in Quantum Field Theory in flat space times due to a basic theorem (CPT Theorem). The currently used formalism of particle physics phenomenology is based on this theorem. However, there may be violations of the basic underlying assumptions of this theorem in models of quantum gravity, namely Lorentz covariance, un...

Twenty years have passed since Tomonaga made his important contribution to quantum electrodynamics. Quantum electrodynamics, although incomplete, is a triumph of quantum field theory applied to the electromagnetic interaction and has served as a model for dealing with the other particle interactions as well. The conspicuous lack of success in the domain of non-electromagnetic interactions has l...

In this paper, a new method to describe the energy spectrums of bound states in Quantum Field Theory is presented. We point out that fundamental field and its dual soliton combine together form corresponds ghost particle our regularization scheme which takes advantage dimensional Pauli-Villars regularization. Based on view, we discuss massive Thirring model, positronium (e+e−) QED vector meson ...

The kinetics of the chiral phase transition is studied within a linear quark-mesonσ model, using a Monte-Carlo approach to semiclassical particle-field dynamics. The meson fields are described on the mean-field level and quarks and antiquarks as ensembles of test particles. Collisions between quarks and antiquarks as well as the qq annihilation to σ mesons and the decay of σ mesons is treated, ...

We consider the Wess-Zumino-Witten theory to obtain the functional integral bosonization of the Thirring-Wess model with an arbitrary regularization parameter. Proceeding a systematic of decomposing the Bose field algebra into gauge-invariantand gauge-noninvariant field subalgebras, we obtain the local decoupled quantum action. The generalized operator solutions for the equations of motion are ...
