GLoBES and its Application to Neutrino Physics

The General Long Baseline Experiment Simulator (GLoBES) is a software package that allows to simulate future neutrino oscillation long baseline experiments and analyze their potential to measure neutrino oscillation parameters. Within GLoBES experiments are described in the Abstract Experiment Definition Language (AEDL) that allows to simulate a variety of different detector technologies and point-like neutrino sources. Thus, besides beam based experiments also neutrino reactor experiments can be simulated. Additionally, very different kinds of systematical uncertainties, e.g. normalization and energy calibration errors can be described and the matter profile along the baseline can be treated accurately including uncertainties. GLoBES provides oscillation probability and event rate calculation as well as simple Δχ2 calculation. More sophisticated GLoBES functions allow to treat the full multi-parameter correlations and degeneracies by the projection of the Δχ2 to planes or axes in the parameter space. Up to 32 experiments can be simulated at once so that synergies between different experiments can be examined. (author)
