Supersymmetric Quantum Field Theory: Indefinite Metric
We study the recently introduced Krein structure (indefinite metric) of the N = 1 supersymmetry and present the way into physical applications outside path integral methods. From the mathematical point of view some perspectives are mentioned at the end of the paper.
متن کاملIndefinite-metric quantum field theory and operator algebra
It is often inevitable to introduce an indefinite-metric space in quantum field theory. There is a problem to determine the metric structure of a given representation space of field operators. We show the systematic method to determine such indefinite-metric explicitly. At first, we choose a new involution ∗ of field operators instead of the original involution † such that there is a Hilbert sp...
متن کاملIs Pseudo-Hermitian Quantum Mechanics an Indefinite-Metric Quantum Theory?
With a view to eliminate an important misconception in some recent publications, we give a brief review of the notion of a pseudo-Hermitian operator, outline pseudo-Hermitian quantum mechanics, and discuss its basic difference with the indefinite-metric quantum mechanics. In particular, we show that the answer to the question posed in the title is a definite No.
متن کاملScattering Theory for Quantum Fields with Indefinite Metric
In this work, we discuss the scattering theory of local, relativistic quantum fields with indefinite metric. Since the results of Haag–Ruelle theory do not carry over to the case of indefinite metric [4], we propose an axiomatic framework for the construction of inand outstates, such that the LSZ asymptotic condition can be derived from the assumptions. The central mathematical object for this ...
متن کاملNontrivial models of quantum fields with indefinite metric
The non perturbative construction of quantum field models with nontrivial scattering in arbitrary dimension d of the underlying Minkowski space-time is much more simple in the framework of quantum field theory with indefinite metric than in the positive metric case. In particular, there exist a number of solutions in the physical dimension d = 4, where up to now no positive metric solutions are...
