Evaluation of a ln tan integral arising in quantum field theory
Abstract
Description
We analytically evaluate a dilogarithmic integral that is prototypical of volumes of ideal tetrahedra in hyperbolic geometry. We additionally obtain new representations of the Clausen function Cl_2 and the Catalan constant G=Cl_2(π/2), as well as new relations between sine and Clausen function values.
