longDescription = ''
The fastNLO project provides computer code to create and evaluate fast
interpolation tables of pre-computed coefficients in perturbation theory
for observables in hadron-induced processes.
This allows fast theory predictions of these observables for arbitrary
parton distribution functions (of regular shape), renormalization or
factorization scale choices, and/or values of alpha_s(Mz) as e.g. needed
in PDF fits or in systematic studies. Very time consuming complete
recalculations are thus avoided.
