I present a definition of the cross section for the production of an isolated photon plus n jets
which only depends upon direct photon production, and it is independent of the parton-to …

I illustrate a general formalism based upon the subtraction method for the calculation of next-
to-leading order QCD cross sections for any number of jets in any type of hard collisions. I …

We present the complete automation of the universal subtraction formalism proposed by
Frixione, Kunszt, and Signer for the computation of any cross section at the next-to-leading …

A bstract We compute the contribution of order α 2 S α 2 to the cross section of a top-antitop
pair in association with at least one heavy Standard Model boson—Z, W±, and Higgs—by …

A bstract In the computation of short-distance cross sections initiated by electrons and
photons one can adopt the so-called structure-function approach, in which these particles …

We discuss the production of W+ W− pairs at hadron colliders with a full O (α s) differential
calculation. The complete analytical result for the partonic cross section is given. We present …

We compute various kinematical distributions for one jet and two jet inclusive
photoproduction at HERA. Our results are accurate to next-to-leading order in QCD. We use …

A bstract The next-to-leading order accuracy for MC@ NLO results exclusive in J light jets is
achieved if the computation is based on matrix elements that feature J and J+ 1 QCD …

The aim of this work is to describe in detail the POWHEG method, first suggested by one of
the authors, for interfacing parton-shower generators with NLO QCD computations. We …

A bstract We present predictions for a variety of single-inclusive observables that stem from
the production of charm and bottom quark pairs at the 7 TeV LHC. They are obtained within …
