I present NNNLO collinear and soft gluon corrections for Higgs production via the process bb̄ → H. I show that the collinear corrections dominate and contribute large enhancements to the cross section at both the Tevatron and the LHC.

I present calculations of soft and collinear corrections to the cross sections for single top quark production, and for Higgs production via bb̄ → H at the Tevatron and the LHC. I show that the corrections provide significant enhancements to the cross sections in both cases. For single top production the soft gluon corrections dominate the cross section, particularly in the s channel and in tW p...

In this paper we compare the prediction for the high energy soft interaction in N-4 SYM with the experimental data. It is shown that at least half of the total cross section at the LHC energy should have a different source than N=4 SYM.

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 ‘crossing’ of next-to-leading order calculations with all partons in the final state. The method introduces universal crossing functions that allow a modular approach to next-to-leading order calculations for any pro...

An overview of recent top quark measurements using the full Run II data set of CDF or D0 at the Tevatron is presented. Results are complementary to the ones at the LHC. Recent measurements of the production cross section of top quarks in strong and electroweak production and of top quark production asymmetries are presented. The latter includes the measurement of the tt̄ production asymmetry by ...

The uncertainty in jet energy scale is one of the dominating systematic errors for many measurements at hadron colliders – most notably for the measurement of the top-quark-mass, inclusive jet cross section measurements and last but not least for events with large missing transverse energy as expected in searches beyond the standard model. This talk will review the approaches taken at Tevatron ...

Muon colliders are expected to naturally have a small spread in beam energy making them an ideal place to study the excitation curve. We present the parameter determinations that are possible from measuring the total cross section near threshold at a μμ collider.

We present a next-to-leading-order calculation of the production of a Z boson with two jets, one or more of which contains a heavy quark (Q = c, b). We show that the cross section with only one heavy-quark jet is larger than that with two heavyquark jets at both the Fermilab Tevatron and the CERN LHC. These processes are the dominant irreducible backgrounds to a Higgs boson produced in associat...

We examine the contributions of soft gluons to the Higgs production cross section at the LHC in the Standard Model and its minimal supersymmetric extension. The soft gluon radiation effects of this reaction share many features with the Drell-Yan process, but arise at lowest order from a purely gluonic initial state. We provide an extension of the conventional soft gluon resummation formalism to...
