Mr Gavin Cullen (University of Edinburgh)14/09/2010, 11:00The status of the Golem project will be reviewed and some recent results will be presented.Go to contribution page

Rikkert Frederix (University of Zurich)14/09/2010, 11:30In 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.Go to contribution page

Isabella Bierenbaum (IFIC Valencia)14/09/2010, 12:30I 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...Go to contribution page

Dr Claude Duhr (IPPP, Durham)15/09/2010, 11:00In 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.Go to contribution page
-
Ignazio Scimemi (UCM)15/09/2010, 11:30In 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.Go to contribution page

Sebastian Sapeta (LPTHE)15/09/2010, 12:00I will present a method, called LoopSim, designed to obtain approximate predictions of the NNLO QCD corrections to the processes with K factors >> 1. The method is based on unitarity and makes use of combining NLO results for different final state multiplicities. After validating the LoopSim procedure against known NNLO results for Drell-Yan lepton $p_t$ spectra I will show approximate NNLO...Go to contribution page

Dr Marco Bonvini (INFN, Sezione di Genova)16/09/2010, 12:00We 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.Go to contribution page

Mr Seyed Mohsen Etesami (Isfahan University of Technology and IPM - Institute for studies in theoretical Physics and Mathematics)17/09/2010, 11:15The 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...Go to contribution page

Elisabetta Furlan (ETH Zurich)17/09/2010, 11:45The 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....Go to contribution page

Sandro Uccirati (Institut für Theoretische Teilchenphysik (TTP) - KIT)17/09/2010, 12:15Starting 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...Go to contribution page

Mr Matthias Kauth (KIT)17/09/2010, 12:45We present new results for the production of gluino pairs at the LHC. Binding effects can make an impact on the cross section around threshold depending on the decay width of a single gluino. Next-to-leading order corrections for the various subprocesses are presented in analytic form together with numerical results. Furthermore, assuming a stable constituent particle the formation of...Go to contribution page
