Hadron Spectroscopy with COMPASS

Abstract

COMPASS is a multi-purpose fixed-target experiment at the CERN Super Proton Synchrotron aimed at studying the structure and spectrum of hadrons. One primary goal is the search for new hadronic states, in particular spin-exotic mesons and glueballs. We present recent results of partial-wave analyses of (3\pi)^- and \pi^-\eta' final states based on a large data set of diffractive dissociation of a 190 GeV/c \pi^- beam on a proton target in the squared four-momentum-transfer range 0.1 < t' < 1 (GeV/c)^2. We also show first results from a partial-wave analysis of diffractive dissociation of K^- into K^-\pi^+\pi^- final states are presented.Comment: 5 pages, 6 figures, proceedings of the "19th Particles and Nuclei International Conference" (PANIC11), MIT, Cambridge, MA, USA, July 24 - 29, 201
