Closed-Form Decomposition of One-Loop Massive Amplitudes
Ruth Britto, Bo Feng, Pierpaolo Mastrolia
We present formulas for the coefficients of 2-, 3-, 4- and 5-point master integrals for one-loop massive amplitudes. The coefficients are derived from unitarity cuts in D dimension…

Integral Coefficients for One-Loop Amplitudes
Ruth Britto, Bo Feng
We present a set of algebraic functions for evaluating the coefficients of the scalar integral basis of a general one-loop amplitude. The functions are derived from unitarity cuts,…

Unitarity Cuts with Massive Propagators and Algebraic Expressions for Coefficients
Ruth Britto, Bo Feng
In the first part of this paper, we extend the d-dimensional unitarity cut method of hep-ph/0609191 to cases with massive propagators. We present formulas for integral reduction wi…
