In this talk, recent progress on the automation of the FKS subtraction method for NLO computations in QCD (within the MadGraph/MadEvent framework) will be discussed.

I present an extension of the duality relation between one-loop integrals and phase-space integrals, developed by S. Catani et al., to higher-order loops. This duality relation is realized by a modification of the customary +i0 prescription of the Feynman propagators and compensates for the absence of multiple-cut contributions that appear in the Feynman tree theorem. I will report on a...

In the planar N=4 supersymmetric Yang-Mills theory, we discuss two-loop amplitudes and Wilson loops at weak coupling, and compare them to the two-loop Wilson loops at strong coupling, which are available in
the literature.

In this talk I will discuss the properties of effective theories of QCD in singular
gauges.
Light-cone gauges in fact are useful in QCD and in the discussion of TMDPDF.
I will discuss how these kind of gauges affect the matrix elements in SCET.

observables at hadron colliders.

We present a phenomenological study of vector boson production at hadron colliders based on NNLO fixed order calculation and on resummation of threshold logarithms. We compare different prescriptions for the calculation of resummed quantities, we study the ambiguity related to the resummation prescription, and we compare it to that coming from scales variation.

The potential of the LHC for investigation of anomalous top quark interactions with gluon
(tug, tcg) through the production of tW-channel of single top quark is studied. In the
Standard Model, the single top quarks in the tW-channel mode are charge symmetric
meaning that (pp ! t + W−) = (pp ! ¯t + W+). However, the presence of anomalous
FCNC couplings leads to charge asymmetry. In this...

The search for the Higgs boson is a primary objective at the Tevatron and the LHC. The dominant production mechanism is gluon fusion, for which new physics effects can lead to significant deviations from the standard model predictions. We consider an extension of the Standard Model in which an arbitrary number of heavy quarks is introduced, and their coupling to the Higgs boson is arbitrary....

Starting from the gauge invariant definition of complex pole, the relation between physical observables measured at LHC and Tevatron and standard model Higgs pseudo-observables is analyzed. This leads to new definitions for the production cross section and the partial decay width, which do not violate first principles. Their computation requires the analytical continuation of Feynman loop...
