ALPGEN, a generator for hard multiparton processes in hadronic collisions

- M. Mangano, M. Moretti, F. Piccinini, R. Pittau, A. Polosa
- Physics
- 28 June 2002

This paper presents a new event generator, ALPGEN, dedicated to the study of multiparton hard processes in hadronic collisions. The code performs, at the leading order in QCD and EW interactions, the… Expand

Reducing full one-loop amplitudes to scalar integrals at the integrand level

- G. Ossola, Costas G.Papadopoulos, R. Pittau
- Physics
- 1 September 2006

Abstract We show how to extract the coefficients of the 4-, 3-, 2- and 1-point one-loop scalar integrals from the full one-loop amplitude of arbitrary scattering processes. In a similar fashion, also… Expand

CutTools: a program implementing the OPP reduction method to compute one-loop amplitudes

- G. Ossola, C. Papadopoulos, R. Pittau
- Physics
- 22 November 2007

We present a program that implements the OPP reduction method to extract the coefficients of the one-loop scalar integrals from a user defined (sub)-amplitude or Feynman Diagram, as well as the… Expand

Physics potential and experimental challenges of the LHC luminosity upgrade

- F. Gianotti, M. Mangano, +48 authors M. Wielers
- Physics
- 8 April 2002

Abstract.We discuss the physics potential and the experimental challenges of an upgraded LHC running at an instantaneous luminosity of 1035 cm-2s-1. The detector R&D needed to operate ATLAS and CMS… Expand

Recursive numerical calculus of one-loop tensor integrals

A numerical approach to compute tensor integrals in one-loop calculations is presented. The algorithm is based on a recursion relation which allows to express high rank tensor integrals as a function… Expand

Automated one-loop calculations: a proof of concept

- A. Hameren, C. Papadopoulos, R. Pittau
- Physics
- 26 March 2009

An algorithm, based on the OPP reduction method, to automatically compute any one-loop amplitude, for all momentum, color and helicity configurations of the external particles, is presented. It has… Expand

On the rational terms of the one-loop amplitudes

- G. Ossola, C. Papadopoulos, R. Pittau
- Physics
- 13 February 2008

The various sources of Rational Terms contributing to the one-loop amplitudes are critically discussed. We show that the terms originating from the generic (n−4)-dimensional structure of the… Expand

- Physics
- 1 June 2019

In response to the 2013 Update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) study was launched, as an international collaboration hosted by CERN. This study cov… Expand

The Higgs Working Group: Summary report

- S. Dawson, M. Grazzini, +56 authors D. Zeppenfeld
- Physics
- 7 June 1999

In this working group we have investigated the prospects for Higgs boson searches at the Tevatron and LHC and, in particular, the potential of these colliders to determine the Higgs properties once… Expand
