N1 - Funding Information:
The research of one of us (M.K.) was supported in part by a grant from the United States–Israel Binational Science Foundation (BSF), Jerusalem and by the Einstein Center for Theoretical Physics at the Weizmann Institute. The research of one of us (H.J.L.) was supported in part by the US Department of Energy, Division of High Energy Physics, Contract W-31-109-ENG-38, We benefited from e-mail discussions with Ken Hicks about the experimental data on the Θ + and with Simon Capstick, Frank Close, Mitya Diakonov, Bob Jaffe and Michał Praszałowicz about the challenges this data poses for a theoretical interpretation. M.K. would like to thank the HEP group at Cavendish Laboratory for hospitality.

N2 - We propose a model for the recently discovered Θ+ exotic K N resonance as a novel kind of a pentaquark with an unusual color structure: a 3c ud diquark, coupled to 3c uds̄ triquark in a relative P-wave. The state has JP = 1/2+, I = 0 and is an antidecuplet of SU(3) f. A rough mass estimate of this pentaquark is close to experiment.
