Decay widths in the massive Schwinger model
نویسنده
چکیده
By a closer inspection of the massive Schwinger model within mass perturbation theory we find that, in addition to the n-boson bound states, a further type of hybrid bound states has to be included into the model. Further we explicitly compute the decay widths of the three-boson bound state and of the lightest hybrid bound state. )permanent address: Inst. f. theoret. Physik d.

The three - boson bound state in the massive Schwinger model
We derive the (matrix-valued) Feynman rules of mass perturbation theory of the massive Schwinger model for non-zero vacuum angle θ. Further, we discuss the properties of the three-boson bound state and compute – by a partial resummation of the mass perturbation series – its mass and its partial decay widths.
متن کاملMassive Schwinger Model within Mass Perturbation Theory∗
In this article we give a detailed discussion of the mass perturbation theory of the massive Schwinger model. After discussing some general features and briefly reviewing the exact solution of the massless case, we compute the vacuum energy density of the massive model and some related quantities. We derive the Feynman rules of mass perturbation theory and discuss the exact n-point functions wi...
متن کاملNote on the Massive Rarita-Schwinger Field in the AdS/CFT Correspondence
We consider a massive Rarita-Schwinger field on the Anti-de Sitter space and solve the corresponding equations of motion. We show that appropriate boundary terms calculated on-shell give two-point correlation functions for spin-3/2 fields of the conformal field theory on the boundary. The relation between Rarita-Schwinger field masses and conformal dimensions of corresponding operators is estab...

The equations of motion for a massive spin2 Rarita-Schwinger field in a finite-range, central, Lorentz scalar potential are developed. It is shown that the resulting density may not be everywhere positive definite.

The complete solution to the massive Rarita-Schwinger field equation in anti-de Sitter space is constructed, and used in the AdS/CFT correspondence to calculate the correlators for the boundary conformal field theory. It is found that when no condition is imposed on the field solution, there appear two different boundary conformal field operators, one coupling to a Rarita-Schwinger field and th...
