From correlation functions to scattering amplitudes
Burkhard Eden, Gregory P. Korchemsky, Emery Sokatchev
We study the correlators of half-BPS protected operators in N=4 super-Yang-Mills theory, in the limit where the positions of the adjacent operators become light-like separated. We…
From correlation functions to Wilson loops
Luis F. Alday, Burkhard Eden, Gregory P. Korchemsky +2
We start with an n-point correlation function in a conformal gauge theory. We show that a special limit produces a polygonal Wilson loop with sides. The limit takes the poi…
Geometrothermodynamics of the Kehagias-Sfetsos Black Hole
W. Janke, D. A. Johnston, R. Kenna
The application of information geometric ideas to statistical mechanics using a metric on the space of states, pioneered by Ruppeiner and Weinhold, has proved to be a useful altern…
Conjugate variables in quantum field theory: the basic case
Klaus Sibold, Gautier Solard
Within standard quantum field theory of one scalar field we define operators conjugate to the energy-momentum operators of the theory. They are singled out by calculational simplic…
Conformal transformations of the S-matrix; -function identifies change of spacetime
S. Pottel, K. Sibold
First conformal transformations of the -matrix are derived in massless -theory. Then it is shown that the anomalous transformations can be rewritten as a symmetry once one…
