Two-component spinors are the basic ingredients for describing fermions in quantum field
theory in 3+ 1 spacetime dimensions. We develop and review the techniques of the two …

In this report we review recent developments in perturbation-theory methods for gauge
theories. We present techniques and results that are useful in the calculation of cross …

and loop-induced interference effects have been computed too, and it was shown that, in the …

We compute for the first time the lepton-pair rapidity distribution in the photon-mediated Drell-
Yan process to next-to-next-to-next-to-leading order in QCD. The calculation is based on the …

We compute the cross section and differential distributions for the production of a Z boson in
association with a hadronic jet to next-to-next-to-leading order (NNLO) in perturbative QCD …

We present a next-to-leading-order calculation of W/Z production interfaced to shower Monte
Carlo, implemented according to the POWHEG method. Finite width effects, Z/γ interference …

A bstract The perturbative description of certain differential distributions across a wide
kinematic range requires the matching of fixed-order perturbation theory with resummation …

We present the first explicit formulæ for the complete set of one-loop helicity amplitudes
necessary for computing next-to-leading order corrections for e+ e− annihilation into four …

We describe a general method of calculating the fully differential cross section for the
production of jets at next-to-leading order in a hadron collider. This method is based on a …

We present the results of a search for the top quark in 19.3 pb− 1 of pp collisions at√ s= 1.8
TeV. The data were collected at the Fermilab Tevatron collider using the Collider Detector at …
