Conformal Field Theory Couplings for Intersecting D-branes on Orientifolds
Abstract We present a conformal field theory calculation of four-point and three-point correlation functions for the bosonic twist fields arising at the intersections of D-branes wrapping (supersymmetric) homology cycles of Type II orientifold compactifications. Both the quantum contribution from local excitations at the intersections and the world-sheet disk instanton corrections are computed....
متن کاملLogarithmic Conformal Field Theory Through Nilpotent Conformal Dimensions
We study logarithmic conformal field theories (LCFTs) through the introduction of nilpotent conformal weights. Using this device, we derive the properties of LCFT’s such as the transformation laws, singular vectors and the structure of correlation functions. We discuss the emergence of an extra energy momentum tensor, which is the logarithmic partner of the energy momentum tensor. PACS: 11.25.Hf
متن کاملOn Conformal Field Theories in Four Dimensions
Extending recent work of Kachru and Silverstein, we consider “orbifolds” of 4-dimensional N = 4 SU(n) super-Yang-Mills theories with respect to discrete subgroups of the SU(4) R-symmetry which act nontrivially on the gauge group. We show that for every discrete subgroup of SU(4) there is a canonical choice of imbedding of the discrete group in the gauge group which leads to theories with a vani...
متن کاملPolylogarithm identities in a conformal field theory in three dimensions
The N = ∞ vector O(N) model is a solvable, interacting field theory in three dimensions (D). In a recent paper with A. Chubukov and J. Ye [1], we have computed a universal number, c̃, characterizing the size dependence of the free energy at the conformally-invariant critical point of this theory. The result [1] for c̃ can be expressed in terms of polylogarithms. Here, we use non-trivial polylogar...
متن کاملCorrelation Functions of a Conformal Field Theory in Three Dimensions
We derive explicit forms of the two–point correlation functions of the O(N) non-linear sigma model at the critical point, in the large N limit, on various three dimensional manifolds of constant curvature. The two–point correlation function, G(x, y), is the only n-point correlation function which survives in this limit. We analyze the short distance and long distance behaviour of G(x, y). It is...
