Abstract
We present the first lattice results of the spectrum of exotic vector mesons extracted from the molecular and diquark-antidiquark operators, with quark fi elds (cq¯ c ¯ q), and (cs¯ ¯ q)/(cq¯¯) respectively, in lattice QCD with exact chiral symmetry. Our results suggest that X(3872) and Y(4260) are in the spectrum of QCD, with J PC = 1 ++ and 1 −− respectively. Moreover, we obtain
