Optimizing the Reduction of One-Loop Amplitudes
P. Mastrolia, G. Ossola, C. G. Papadopoulos +1
We present an optimization of the reduction algorithm of one-loop amplitudes in terms of master integrals. It is based on the exploitation of the polynomial structure of the integr…
The NLO multileg working group: summary report
Z. Bern, S. Dittmaier, L. Dixon +44
This report summarizes the activities of the NLM working group of the Workshop "Physics at TeV Colliders", Les Houches, France, 11-29 June, 2007.
On the Rational Terms of the one-loop amplitudes
Giovanni Ossola, Costas G. Papadopoulos, Roberto Pittau
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 struct…
A new method for the numerical evaluation of one-loop amplitudes
Giovanni Ossola
We recently presented a new method for the evaluation of one-loop amplitude of arbitrary scattering processes, in which the reduction to scalar integrals is performed at the integr…
Dynamic critical behavior of the Chayes-Machta-Swendsen-Wang algorithm
Youjin Deng, Timothy M. Garoni, Jonathan Machta +3
We study the dynamic critical behavior of the Chayes-Machta dynamics for the Fortuin-Kasteleyn random-cluster model, which generalizes the Swendsen-Wang dynamics for the q-state Po…
Bounds on the Higgs Boson Mass from M_W
A. Ferroglia, G. Ossola, A. Sirlin
Recent experimental and theoretical progress in the M_H estimates from M_W and Sin^2_eff_lept is reviewed, with particular emphasis on the role played by M_t. Assuming that the SM…
