Unitary, anomalous Master Ward Identity and its connections to the Wess-Zumino condition, BV formalism and -algebras
Romeo Brunetti, Michael Dütsch, Klaus Fredenhagen +1
The C*-algebraic construction of QFT by Buchholz and one of us relies on the causal structure of spacetime and a classical Lagrangian. In one of our previous papers we have introdu…
The unitary Master Ward Identity: Time slice axiom, Noether's Theorem and Anomalies
Romeo Brunetti, Michael Dütsch, Klaus Fredenhagen +1
The C*-algebraic formulation of generic interacting quantum field theories, recently presented by Detlev Buchholz and one of the authors (KF), is enriched by a unitary version of t…
-algebraic approach to interacting quantum field theory: Inclusion of Fermi fields
Romeo Brunetti, Michael Dütsch, Klaus Fredenhagen +1
We extend the -algebraic approach to interacting quantum field theory, proposed recently by Detlev Buchholz and one of us (KF) to Fermi fields. The crucial feature of our appr…
The scaling and mass expansion
Michael Duetsch
The scaling and mass expansion (shortly 'sm-expansion') is a new axiom for causal perturbation theory, which is a stronger version of a frequently used renormalization condition in…
Generalized free fields and the AdS-CFT correspondence
M. Duetsch, K. -H. Rehren
Motivated by structural issues in the AdS-CFT correspondence, the theory of generalized free fields is reconsidered. A stress-energy tensor for the generalized free field is constr…
