dc.descriptionSince all couplings of the exotic $Θ^+$ baryon to normal hadrons seem to be small it is hard to reveal it in standard resonance searching. We suggest to look for the $Θ^+$ production in interference with a known resonance yielding the same final state but having a high production rate. The interference process is linear in the $Θ^+$ couplings whereas the non-interference process is quadratic. That gives an obvious gain if the couplings are small. Moreover, employing the peculiar oscillating nature of the interference processes one can reduce considerably the parasitic background and determine the $Θ^+$ resonance parameters.
