Single-top t-channel hadroproduction in the four-flavour scheme with POWHEG and aMC@NLO
نویسندگان
چکیده
We present results for the QCD next-to-leading order (NLO) calculation of single-top t-channel production in the 4-flavour scheme, interfaced to Parton Shower (PS) Monte Carlo programs according to the POWHEG and MC@NLO methods. Comparisons between the two methods, as well as with the corresponding process in the 5-flavour scheme are presented. For the first time results for typical kinematic distributions of the spectator-b jet are presented in an NLO+PS approach.

This note documents the use of the POWHEG-hvq package, a generator for heavy flavour hadroproduction at next-to-leading order in QCD, that can be easily interfaced to shower Monte Carlo programs, in such a way that NLO and shower accuracy are both maintained.

We present a next-to-leading order calculation of single-top production interfaced to Shower Monte Carlo programs, implemented according to the POWHEG method. A detailed comparison with MC@NLO and PYTHIA is carried out for several observables, for the Tevatron and LHC colliders.

I review recent developments and applications of the POWHEG method, to merge NLO calculations with Shower Monte Carlo programs, in the POWHEG-BOX framework. Particular emphasis is given to the recent implementation of the top-quark pairs hadroproduction in association with a hard jet. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike...
متن کاملA Positive-Weight Next-to-Leading-Order Monte Carlo for Heavy Flavour Hadroproduction
We present a next-to-leading order calculation of heavy flavour production in hadronic collisions that can be interfaced to shower Monte Carlo programs. The calculation is performed in the context of the POWHEG method [1]. It is suitable for the computation of charm, bottom and top hadroproduction. In the case of top production, spin correlations in the decay products are taken into account.
متن کاملMatching NLO QCD and Parton Showers in Heavy Flavour Production∗
We apply the MC@NLO approach to the process of heavy flavour hadroproduction. MC@NLO is a method for matching next-to-leading order (NLO) QCD calculations and parton shower Monte Carlo (MC) simulations, with the following features: fully exclusive events are generated, with hadronisation according to the MC model; total rates are accurate to NLO; NLO results for distributions are recovered upon...
