Abstract
We investigate the mass spectrum of 1+ exotic mesons with quark content () or (), using molecular and diquark-antidiquark operators, in quenched lattice QCD with exact chiral symmetry. For the molecular operator (γi)(γ5)-(γi)(γ5) and the diquark-antidiquark operator (T C γi )( C γ5 T)- (T C γ5 )( C γiT T), both detect a 1+ resonance with mass around 4010 +- 50 MeV in the limit mq -> mu,d.
