Analytic \varepsilon -Expansion of the Scalar One-Loop Bhabha Box Function

J. Fleischer, T. Riemann, O.V. Tarasov

We derive the first three terms of the \varepsilon -expansion of the scalar one-loop Bhabha box function from a representation in terms of three generalized hypergeometric functions, which is valid in arbitrary dimensions.
