A general algorithm for calculating jet cross sections in NLO QCD

- S. Catani, M. Seymour
- Physics
- 15 May 1996

We present a new general algorithm for calculating arbitrary jet cross sections in arbitrary scattering processes to next-to-leading accuracy in perturbative QCD. The algorithm is based on the… Expand

The singular behaviour of QCD amplitudes at two-loop order

- S. Catani
- Physics
- 26 February 1998

Abstract We discuss the structure of infrared singularities in on-shell QCD amplitudes at two-loop order. We present a general factorization formula that controls all the ϵ-poles of the dimensionally… Expand

The Dipole Formalism for Next-to-Leading Order QCD Calculations with Massive Partons

- S. Catani, S. Dittmaier, M. Seymour, Z. Trocsanyi
- Physics
- 7 January 2002

Abstract The dipole subtraction method for calculating next-to-leading order corrections in QCD was originally only formulated for massless partons. In this paper we extend its definition to include… Expand

QCD Matrix Elements + Parton Showers

We propose a method for combining QCD matrix elements and parton showers in Monte Carlo simulations of hadronic flnal states in e + e i annihilation. The matrix element and parton shower domains are… Expand

The dipole formalism for the calculation of QCD jet cross sections at next-to-leading order

- S. Catani, M. Seymour
- Physics
- 12 February 1996

In order to make quantitative predictions for jet cross sections in perturbative QCD, it is essential to calculate them to next-to-leading accuracy. This has traditionally been an extremely laborious… Expand

Resummation of large logarithms in e+ e- event shape distributions

- S. Catani, L. Trentadue, G. Turnock, B. Webber
- Physics
- 11 October 1993

Abstract We describe a method for the resummation of leading and next-to-leading large logarithms to all orders in QCD perturbation theory, applicable to e + e − event shape distributions that have… Expand

Vector boson production at hadron colliders: a fully exclusive QCD calculation at next-to-next-to-leading order.

- S. Catani, L. Cieri, G. Ferrera, D. de Florian, M. Grazzini
- Physics, Medicine
- Physical review letters
- 12 March 2009

We consider QCD radiative corrections to the production of W and Z bosons in hadron collisions. We present a fully exclusive calculation up to next-to-next-to-leading order (NNLO) in QCD perturbation… Expand

Longitudinally-invariant k ⊥ -clustering algorithms for hadron-hadron collisions

- S. Catani, Y. Dokshitzer, M. Seymour, B. Webber
- Physics
- 27 September 1993

Abstract We propose a version of the QCD-motivated “k⊥” jet-clustering algorithm for hadron-hadron collisions which is invariant under boosts along the beam directions. This leads to improved… Expand

QCD coherent branching and semi-inclusive processes at large χ

- S. Catani, B. Webber, G. Marchesini
- Physics
- 11 February 1991

Using the QCD coherent branching algorithm, we compute the Deep Inelastic Scattering and Drell-Yan hard cross sections in the semi-inclusive region of large χ. The calculation is done to… Expand

Next-to-next-to-leading-order subtraction formalism in hadron collisions and its application to Higgs-boson production at the large hadron collider.

- S. Catani, M. Grazzini
- Physics, Medicine
- Physical review letters
- 1 March 2007

We consider higher-order QCD corrections to the production of colorless high-mass systems (lepton pairs, vector bosons, Higgs bosons, etc.) in hadron collisions. We propose a new formulation of the… Expand
