After having started to study the existence of the spin-exotic $\\pi_1(1600)$ resonance in the 2004 pilot-run data, the new 2008/09 data will enable us to further clarify the situation. Apart from the $\\pi_1(1600)$ resonance, also a spin-exotic $\\pi_1(2000)$ was reported in the past in the $f_1(1285)\\pi$ decay channel by the E852/BNL experiment, however, this state still lacks confirmation. We present a first event selection of the diffractively produced $(K\\bar{K}\\pi\\pi)^{-}$ system showing clean $f_1(1285)$ and $f_1(1420)$ resonances at competing statistics. A partial-wave analysis started on $f_1(1285)\\pi$ and $f_1(1420)\\pi$ decay channels will further complete the search for spin-exotics in the 2008/09 COMPASS data.", "revisions": [ { "version": "v1", "updated": "2011-09-01T15:45:59.000Z" } ], "analyses": { "keywords": [ "final states", "diffractive dissociation", "decay channel", "first event selection", "compass fixed-target experiment" ], "tags": [ "conference paper" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "inspire": 926044, "adsabs": "2011arXiv1109.0219B" } } }
