Query: Baryon Spectroscopy at COMPASS   At the COMPASS experiment, diffractive dissociation of the beam proton is one
of the dominant processes for the 190GeV/c positive hadron beam impinging on a
liquid hydrogen target. The status of the analysis of the reactions pp -> p_f
pi^+ pi^- p_s and pp -> p_f K^+ K^- p_s is presented, where dominant features
of the light-baryon spectrum become clearly visible. Furthermore, partial-wave
analysis techniques to disentangle these spectra are discussed.
