Three-Jet Cross Section in Hadron Collisions at Next-to-Leading Order: Pure Gluon Processes.
The next-to-leading order three-jet cross section in hadron collisions is calculated in the simplified case when the matrix elements of all QCD subprocesses are approximated by the pure gluon matrix element. The longitudinallyinvariant k⊥ jet-clustering algorithm is used. The important property of reduced renormalization and factorization scale dependence of the next-toleading order physical cr...
متن کاملNext to Leading Order Three Jet Production at Hadron Colliders
I present results from a next-to-leading order event generator of purely gluonic jet production. This calculation is the first step in the construction of a full next-to-leading order calculation of three jet production at hadron colliders. Several jet algorithms commonly used in experiments are implemented and their numerical stability is investigated. A numerical instability is found in the i...
متن کاملHiggs-Boson production at hadron colliders: differential cross sections through next-to-next-to-leading order.
We present a calculation of the fully differential cross section for Higgs-boson production in the gluon fusion channel through next-to-next-to-leading order (NNLO) in perturbative QCD. We apply the method introduced in Phys. Rev. D 69, 076010 (2004)] to compute double real emission corrections. Our calculation permits arbitrary cuts on the final state in the reaction hh-->H+X. It can easily be...
متن کاملJet Cross Sections at Next-to-leading Order *
We briefly summarize theoretical methods for carrying out QCD calculations to next-to-leading order in perturbation theory. In particular, we describe a new general algorithm that can be used for computing arbitrary jet cross sections in arbitrary processes and can be straightforwardly implemented in general-purpose Monte Carlo programs. CERN-TH/96-342 December 1996 ∗Invited talk presented at t...
متن کاملHigher Order Corrections to Jet Cross Sections in Hadron Colliders
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...
