[D7.010] Search for the \Theta^- with PHENIX

Christopher Pinkenburg (Brookhaven National Laboratory), PHENIX Collaboration

There is mounting evidence for the existance of exotic hadrons consisting of 5 quarks. Resonance states have been observed in K^+ and pK^0_s invariant mass spectra near 1.540 GeV/c^2 (Q^+) and in \Xi-\pi invariant mass spectra around 1.86 GeV/c^2 (\Xi^--).

PHENIX has in principle the ability to reconstruct the Q^- in the øverlinenK^- channel. In addition to identifying charged particles, PHENIX can detect anti-neutrons with its highly segmented electromagnetic calorimeter. Using these capabilities we can perform a search for the Q^-. The current state of this search will be presented.
