Perturbation theory for the two-dimensional abelian Higgs model in the unitary gauge
In the unitary gauge the unphysical degrees of freedom of spontaneously broken gauge theories are eliminated. The Feynman rules are simpler than in other gauges, but it is nonrenormalizable by the rules of power counting. On the other hand, it is formally equal to the limit ξ → 0 of the renormalizable Rξ-gauge. We consider perturbation theory to one-loop order in the Rξ-gauge and in the unitary...
متن کاملUniversality in Two Dimensional Gauge Theory
We discuss two dimensional Yang – Mills theories with massless fermions in arbitrary representations of a gauge group G. It is shown that the physics (spectrum and interactions) of the massive states in such models is independent of the detailed structure of the model, and only depends on the gauge group G and an integer k measuring the total anomaly. The massless physics, which does depend on ...
متن کاملTwo-Dimensional Gravity and Nonlinear Gauge Theory
We construct a gauge theory based on nonlinear Lie algebras, which is an extension of the usual gauge theory based on Lie algebras. It is a new approach to generalization of the gauge theory. The two-dimensional gravity is derived from nonlinear Poincaré algebra, which is the new Yang-Mills like formulation of the gravitational theory. As typical examples, we investigate R2 gravity with dynamic...
متن کاملPerturbation theory for weakly coupled two-dimensional layers
A key issue in two-dimensional structures composed of atom-thick sheets of electronic materials is the dependence of the properties of the combined system on the features of its parts. Here, we introduce a simple framework for the study of the electronic structure of commensurate and incommensurate layered assemblies based on perturbation theory. Within this framework, we calculate the band str...
متن کاملPerturbation theory in two-dimensional open string field theory.
In this paper we develop the covariant string field theory approach to open 2d strings. Upon constructing the vertices, we apply the formalism to calculate the lowest order contributions to the 4-and 5-point tachyon–tachyon tree amplitudes. Our results are shown to match the 'bulk' amplitude calculations of Bershadsky and Kutasov. In the present approach the pole structure of the amplitudes bec...
