The three - boson bound state in the massive Schwinger model
نویسنده
چکیده
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.

Decay widths in the massive Schwinger model
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. Uni Wien Boltzman...
متن کاملThe boson-boson bound state in the massive Schwinger model
We use (fermion) mass perturbation theory for the massive Schwinger model to compute the boson-boson bound state mass in lowest order. For small fermion mass the lowest possible Fock state turns out to give the main contribution and leads to a second order result for the bound state mass. ∗)permanent address: Institut für theoretische Physik, Universität Wien Boltzmanngasse 5, 1090 Wien, Austri...
متن کاملThe (1+1)-dimensional Massive sine-Gordon Field Theory and the Gaussian Wave-functional Approach
The ground, oneand two-particle states of the (1+1)-dimensional massive sine-Gordon field theory are investigated within the framework of the Gaussian wave-functional approach. We demonstrate that for a certain region of the model-parameter space, the vacuum of the field system is asymmetrical. Furthermore, it is shown that two-particle bound state can exist upon the asymmetric vacuum for a par...
متن کاملInstanton modifications of the bound state singularity in the Schwinger Model
We consider the quark-antiquark Green’s function in the Schwinger Model with instanton contributions taken into account. Thanks to the fact that this function may analytically be found, we draw out singular terms, which arise due to the formation of the bound state in the theory — the massive Schwinger boson. The principal term has a pole character. The residue in this pole contains contributio...
متن کاملMesons in the massive Schwinger model on the light cone.
We investigate mesons in the bosonized massive Schwinger model in the light-front Tamm-Dancoff approximation in the strong coupling region. We confirm that the three-meson bound state has a few percent fermion six-body component in the strong coupling region when expressed in terms of fermion variables, consistent with our previous calculations. We also discuss some qualitative features of the ...
