found in Part I within the boxed pages. As complete files, they are also available in the
GLoBES software package.
The GLoBES software may have two target groups: Physicists, who are mainly interested in optimizing the potential of specific experimental setups, and others, who are mainly
interested in the physics potential of different experiment types from a theoretical point of
view. For the first group, AEDL could be the most interesting aspect of GLoBES, where the
user interface is only a tool to obtain specific parameter sensitivities. In this case, GLoBES
could, serve as a unified tool for the comparison and optimization of different experiment
setups on equal footing, where it is the primary objective to simulate the experiments as
accurate as possible. In addition, changes in experimental parameters, such as efficiencies
or the energy resolutions, can quickly be tested. For the second user group, the pre-defined
experiment definition files might already be sufficient to test new conceptual approaches,
and the user interface is the most interesting aspect for sophisticated applications including correlations, degeneracies, and multi-experiment setups. In either case, the GLoBES
software could serve as a platform for the exchange of experiment definitions, and for an
efficient splitting of work between experimentalists and theorists.
The user interface functions are described in Part I of this manual, which is the “user’s
manual”. In there, first of all a short GLoBES tour is given in Chapter 1 in order to have an
overview over GLoBES. After that, the user interface is successively introduced from very
basic to more sophisticated functions. Eventually, it is demonstrated how one can change
many experiment parameters at running time (such as baseline or target mass), and how
one can obtain low-level information. We recommend that everybody interested in GLoBES
should become familiar at least with the concepts in Chapter 1 and some of the examples
on the boxed pages. The examples can be directly compiled from the respective directory
in the GLoBES software package.
In Part II of the manual, AEDL is described. After an introductory chapter, all functions
are defined in greater detail. This part might be more interesting for the experimental
users who want to modify or create AEDL files. A useful tool in this context is the software
program globes, which returns event rates and other information for individual AEDL
files without further programming. For example, flux normalizations can with this tool be
easily adjusted to reproduce the event rates of a specific experiment. It is described in the
last chapter of Part II.
Note: All examples for application software in C do require a C++ compiler to be properly compiled. For pedagogical reasons, variable declarations are done at that place where
the variable is needed for the first time, which is at variance with C syntax but not with
C++ syntax. That is the only way in which the examples deviate form ISO C. Moreover
the actual numerical values of the results of the examples may be different from the ones
in this manual.
