Spectroscopy of final states with neutral particles in COMPASS — •Sebastian Uhl1 and COMPASS Collaboration2 — 1Technische Universität München — 2CERN
In order to study the spectrum of light hadrons, the COMPASS experiment at CERN has collected a huge data set with a negative pion beam impinging on a liquid hydrogen target. Resonances are diffractively produced at squared four-momentum transfers to the target between 0.1 and 1 (GeV/c)2. The two-stage magnetic spectrometer with two electromagnetic calorimeters allows to study in particular channels with neutral particles in the final states. We will report on recent results.
