چکیده
We sketch the architecture of O’Mega, a new optimizing compiler for tree amplitudes in quantum field theory, and briefly describe its usage. O’Mega generates the most efficient code currently available for scattering amplitudes for many polarized particles in the Standard Model and its extensions. e-mail: [email protected] e-mail: [email protected] e-mail: [email protected]

O’Mega & WHIZARD: Monte Carlo Event Generator Generation For Future Colliders
I describe the optimizing matrix element generator O’Mega [1, 2] and Wolfgang Kilian’s event generator generator WHIZARD [3]. These tools cooperate in the automated production of efficient unweighted event generators for linear collider physics.
متن کاملEXCALIBUR – a Monte Carlo program to evaluate all four fermion processes at LEP 200 and beyond 1
A Monte Carlo program is presented that computes all four fermion processes in e + e − annihilation. QED initial state corrections and QCD contributions are included. Fermions are taken to be massless, allowing a very fast evaluation of the matrix element. A systematic, modular and self-optimizing strategy has been adopted for the Monte Carlo integration, that serves also as an example for furt...
متن کاملA modified CKKW matrix element merging approach to angular-ordered parton showers
A modified version of the CKKW matrix element merging algorithm is presented, suitable for use in an angular-ordered parton shower, using truncated showers and forced splittings. The algorithm is implemented in the Herwig++ Monte Carlo event generator for the benchmark process e+e− → hadrons. Results are presented at parton and hadron levels, demonstrating a smooth merging between the matrix el...
متن کاملMatrix-Variate Beta Generator - Developments and Application
Matrix-variate beta distributions are applied in different fields of hypothesis testing, multivariate correlation analysis, zero regression, canonical correlation analysis and etc. A methodology is proposed to generate matrix-variate beta generator distributions by combining the matrix-variate beta kernel with an unknown function of the trace operator. Several statistical characteristics, exten...
متن کاملComix∗, a new matrix element generator
We present a new tree-level matrix element generator, based on the colour dressed Berends-Giele recursive relations. We discuss two new algorithms for phase space integration, dedicated to be used with large multiplicities and colour sampling.
