48. ATLAS and CMS: status and first results

28. Single-cut spinor integration and tadpole coefficients

Edoardo Mirabella (Institut de Physique Théorique, CEA)

14/09/2010, 15:15

I report on work done in collaboration with Ruth Britto. I will present the extension of the spinor integration formalism for one-loop amplitudes from the double-cut to the single-cut case. I will show how this technique can be applied for the computation of tadpole coefficients, which arise in a master integral expansion if massive particles circulate in the loop. When massive particles...

18. Z-boson pair + 1-jet production at NLO QCD

Nikolas Kauer (RHUL)

14/09/2010, 15:45

A fully differential calculation of the next-to-leading order QCD corrections to the production of $Z$-boson pairs in association with a hard jet at the Tevatron and LHC is presented. This process is an important background for Higgs particle and new physics searches at hadron colliders. We find sizable corrections for cross sections and differential distributions, particularly at the...

5. NNLO jet cross sections by subtraction

Gabor Somogyi (DESY, Zeuthen)

15/09/2010, 14:30

We report on recent progress in integrating the approximate cross sections over the phase space of unresolved partons of the general NNLO subtraction scheme of Del Duca, Somogyi and Trocsanyi. In particular, we discuss the computation of a class of integrals that arise when integrating the so-called iterated singly-unresolved approximate cross section. The integrated cross section can be...

11. NNLO antenna subtraction with one hadronic initial state

Gionata Luisoni (Universität Zürich)

15/09/2010, 15:00

In this talk we present the extension of the antenna subtraction method to include initial states containing one hadron at NNLO. We sketch the requirements for the different necessary subtraction terms, and we explain how the antenna functions are integrated over the appropriate phase space by reducing the integrals to a small set of master integrals. Where applicable, our results for the...

25. The ttbar total cross section at hadron colliders at NNLL

Mr Sebastian Klein (RWTH Aachen)

16/09/2010, 14:45

Using the SCET--formalism, we perform threshold resummation in x--space for top--quark pair production at hadron colliders. Our analysis extends to NNLL, including soft and coulomb gluon resummation. Results for the total cross section of t-tbar production at the LHC and the Tevatron are presented.
