Recursive generation of one-loop SM amplitudes — Stefano Actis¹, Ansgar Denner², •Lars Hofer², Andreas Scharf², and Sandro Uccirati³ — ¹Paul Scherrer Institut, Würenlingen und Villigen — ²Universität Würzburg — ³Universita di Torino

We introduce the computer code Recola for the recursive generation of tree-level and one-loop amplitudes in the full Standard Model, including electroweak corrections. The presented algorithm for the calculation of one-loop amplitudes uses Dyson-Schwinger recursion relations to determine the coefficients of the tensor integrals. As a first application of Recola we discuss Z+2jets production at the LHC and present results for the next-to-leading-order electroweak corrections to the dominant partonic channels.
