The transverse-momentum distribution of the Higgs boson at the LHC

We present QCD predictions for the transverse momentum (q_T) distribution of the Higgs boson at the LHC. At small q_T the logarithmically-enhanced terms are resummed to all orders up to next-to-next-to-leading logarithmic accuracy. The resummed component is consistently matched to the next-to-leading order calculation valid at large q_T. The results, which implement the most advanced perturbative predictions available at present for this observable, show a good stability with respect to theoretical uncertainties. The numerical program HqT, used to perform the calculation, is briefly discussed.Comment: 4 pages, 2 figures, to appear in the Proceedings of the International Europhysics Conference on High Energy Physics, July 21st - 27th 2005, Lisboa, Portuga

Consistent Estimation of Agent Based Models

The aim of this paper is to describe a method to introduce empirical data in agent based models. Starting from the econometric and calibration literature, it is shown how to select the values of the parameters in the model and which conditions has to be met to have consistent estimations. A crucial point lays in the analysis of the artificial data produced by model, in particular to test for ergodicity and stationarity.Agent-based models, Estimation, Calibration, Simulation
