One of the main challenges of hadron physics is the search for new hadronic states. Apart from conventional states also exotics, such as glueballs or hybrids, are realizable. In order to experimentally verify and classify hadronic states, an amplitude analysis is often mandatory. The analysis and comparison of data from multiple experiments is particularly interesting.
The new amplitude analysis framework ComPWA was specifically created to satisfy such demands and set new standards in the amplitude analysis frontier. Its modular design allows flexible amplitude analysis and framework extensions, most importantly the physics models and formalisms. Interfaces to the optimization libraries Minuit2 and Geneva are available. The ComPWA framework was already used for analysis of BESIII data. Since ComPWA is not specifically bound to any experiment, amplitude analysis of data from future experiments like PANDA are also awaited.
This talk presents the possibilities of the ComPWA framework, the current status and the ongoing development.
