Unbiased determination of the proton structure function F-2(p) with faithful uncertainty estimation / L. Del Debbio, S. Forte, J.I. Latorre, A. Piccione, J. Rojo. - In: JOURNAL OF HIGH ENERGY PHYSICS. - ISSN 1029-8479. - 2005:3(2005), pp. 080.1-080.19. [10.1088/1126-6708/2005/03/080]
Abstract:
We construct a parametrization of the deep-inelastic structure function of the proton F-2(x, Q(2)) based on all available experimental information from charged lepton deep-inelastic scattering experiments. The parametrization effectively provides a bias-free determination of the probability measure in the space of structure functions, which retains information on experimental errors and correlations. The result is obtained in the form of a Monte Carlo sample of neural networks trained on an ensemble of replicas of the experimental data. We discuss in detail the techniques required for the construction of bias-free parameterizations of large amounts of structure function data, in view of future applications to the determination of parton distributions based on the same method.
