Recoil-safe subtraction, matching and merging in e+e− → hadrons
Abstract
A bstract We present the first next-to-leading order matched and multi-jet merged predictions based on the A laric parton shower. The components needed for infrared subtraction in the S-M c @N lo algorithm are computed analytically for the case of color singlet decays to hadronic final states and validated against existing approaches for up to e − e + → 5 jets. Phenomenological results for e − e + → hadrons at the Z pole are obtained with up to five jets at next-to-leading order precision, for the first time using an evolution algorithm with NLL-preserving kinematics mapping.
