Pole structure and biharmonic fields in conformal QFT in four dimensions
N. M. Nikolov, K. -H. Rehren, I. Todorov
Imposing Huygens' Principle in a 4D Wightman QFT puts strong constraints on its algebraic and analytic structure. These are best understood in terms of ``biharmonic fields'', whose…
Globally conformal invariant gauge field theory with rational correlation functions
Nikolay M. Nikolov, Yassen S. Stanev, Ivan T. Todorov
Operator product expansions (OPE) for the product of a scalar field with its conjugate are presented as infinite sums of bilocal fields V_k (x_1, x_2) of dimension (k,k). For a {\i…
Four Dimensional CFT Models with Rational Correlation Functions
Nikolay M. Nikolov, Yassen S. Stanev, Ivan T. Todorov
Recently established rationality of correlation functions in a globally conformal invariant quantum field theory satisfying Wightman axioms is used to construct a family of soluble…
Regular basis and R-matrices for the su(n)_k Knizhnik-Zamolodchikov equation
L. K. Hadjiivanov, Ya. S. Stanev, I. T. Todorov
Dynamical R-matrix relations are derived for the group-valued chiral vertex operators in the SU(n) WZNW model from the KZ equation for a general four-point function including two s…
coherent state operators and invariant correlation functions and their quantum group counterparts
H. Sazdjian, Y. S. Stanev, I. T. Todorov
Coherent state operators (CSO) are defined as operator valued functions on G=SL(n,C), homogeneous with respect to right multiplication by lower triangular matrices. They act on a m…
