• COMPASS is a fixed target experiment at CERN with high energy muon and hadron beams delivered by SPS. Hadron spectroscopy focusing onto search for exotics states in meson sector is one of the main topics within the experiment. Two production mechanisms are used in the search for exotic states: diffractive dissociation and central production using a liquid hydrogen target and nuclear targets. Following the first data taking performed in 2004 with nuclear targets, main part of the data has been taken in 2008 and 2009 with a hydrogen target. The PWA for the 2004 data of the diffractively produced charged 3π shows the existence of an exotic state at a mass around 1.6GeV. In this paper, we report on the analysis and show first insights into the results using various final states.
