Description
A large part of the physics program of the PANDA experiment at FAIR
deals with the search for new conventional and exotic hadronic states
like e.g. hybrids and glueballs. In a majority of analyses PANDA will
need a Partial Wave Analsis (PWA) to identify possible candidates and
for the classification of known states. Therefore, a new, agile and
efficient PWA-Framework will be developed. It will be modularized to
provide easy extension with models and formalisms as well as fitting of
multiple datasets, even from different experiments. Experience from
existing PWA programs was used to fix the requirements of the framwork
and to prevent it from restrictions. It will provide various estimation
and optimization routines like Minuit2 and the Geneva library. The
challenges involve parallelization, fitting with a high number of free
parameters, managing complex meta-fits and quality assurance /
comparability of fits. To test the software, it will be used with data
from running experiments like BaBar or BESIII. The presentation will
show the status of the framework implementation as well as first tests.
