Infinite dimensional Lie algebras in 4D conformal quantum field theory
B. Bakalov, N. M. Nikolov, K. -H. Rehren +1
The concept of global conformal invariance (GCI) opens the way of applying algebraic techniques, developed in the context of 2-dimensional chiral conformal field theory, to a highe…
Harmonic bilocal fields generated by globally conformal invariant scalar fields
Nikolay M. Nikolov, Karl-Henning Rehren, Ivan Todorov
The twist two contribution in the operator product expansion of phi_1(x_1) phi_2(x_2) for a pair of globally conformal invariant, scalar fields of equal scaling dimension d in four…
Partial wave expansion and Wightman positivity in conformal field theory
N. M. Nikolov, K. -H. Rehren, I. T. Todorov
A new method for computing exact conformal partial wave expansions is developed and applied to approach the problem of Hilbert space (Wightman) positivity in a non-perturbative fou…
Global Conformal Invariance and Bilocal Fields with Rational Correlation Functions
Nikolay M. Nikolov, Yassen S. Stanev, Ivan T. Todorov
The singular part of the \textit{operator product expansion} (OPE) of a pair of \textit{globally conformal invariant} (GCI) scalar fields of (integer) dimension can be writ…
Rationality of conformally invariant local correlation functions on compactified Minkowski space
Nikolay M. Nikolov, Ivan T. Todorov
Rationality of the Wightman functions is proven to follow from energy positivity, locality and a natural condition of global conformal invariance (GCI) in any number D of space-tim…
