ON THE IR-FINITENESS OF THE NONLINEAR O(N) σ-MODEL

Autor: H. Balasin, Olivier Piguet, Wolfgang Kummer, Manfred Schweda

Publikováno v: Modern Physics Letters A. :3487-3493

Using the proper definition1 of the massless 2D-propagator – depending on an arbitrary ir-scale μ – we check Elitzur’s conjecture on the ir finiteness of O(N)-invariant Green functions. Explicit computations to the second order in the coupling

On the regularization of the mass-zero 2D-propagator

Autor: Olivier Piguet, H. Balasin, Manfred Schweda, Wolfgang Kummer

Publikováno v: Physics Letters B. 287:138-144

The propagator of the two-dimensional massless field theory is properly defined (in the sense of tempered distributions). Different regularizations are discussed and sample loop calculations using these regularizations are performed.

The action principle revisited

Autor: M. Stierle, H. Balasin

Publikováno v: Journal of Mathematical Physics. 32:1376-1382

The form of Schwinger’s action principle within the BPHZ method is investigated and some loopholes in the usual proofs are closed.

Extended BRS symmetry in a class of linear gauges

Autor: H. Balasin, M. Stierle, M. Schweda

Publikováno v: Physical review. D, Particles and fields. 42(4)

We investigate the renormalizability and the gauge (in)dependence of a pure Yang-Mills theory in a class of linear gauges interpolating between covariant and noncovariant ones.

Comments on the proof of the renormalized action principle

Autor: H. Balasin

Publikováno v: Physical and Nonstandard Gauges ISBN: 9783540528159

The action principle holds a central position in renormalized field theory, since it controls the variation of renormalized Green's functions with respect to field transformations (important examples are the Ward-Takahashi and the Slavnov-Taylor-iden
