The COMPASS fixed-target experiment at CERN/SPS is dedicated to the study of
hadron structure and spectroscopy, especially the search for spin-exotic
states. After having started to study the existence of the spin-exotic
Ο1β(1600) resonance in the 2004 pilot-run data, the new 2008/09 data will
enable us to further clarify the situation. Apart from the Ο1β(1600)
resonance, also a spin-exotic Ο1β(2000) was reported in the past in the
f1β(1285)Ο decay channel by the E852/BNL experiment, however, this state
still lacks confirmation. We present a first event selection of the
diffractively produced (KKΛΟΟ)β system showing clean f1β(1285)
and f1β(1420) resonances at competing statistics. A partial-wave analysis
started on f1β(1285)Ο and f1β(1420)Ο decay channels will further
complete the search for spin-exotics in the 2008/09 COMPASS data.Comment: 4 pages, 6 figures, Hadron2011 Conference Proceedings, to appear in
