Abstract
The light meson regime still is not too well understood and holds many open questions that can only be answered using sophisticated analysis strategies to describe the data. In particular, searching and investigating exotic states, e.g., glueballs, hybrids and tetraquarks is a challenge among the many broad and overlapping resonances. Combining data of different production mechanisms in coupled channel partial wave analyses, as, e.g., gluon-poor two-photon fusion events and gluon-rich reactions, helps to disentangle the highly populated light meson spectrum. To do so, sophisticated dynamical models need to be applied respecting unitarity and analyticity. Such models are, among others, implemented in the here used par�tial wave analysis package PAWIAN. Applied methods together with new results on coupled channel analyses are discussed.
