We present the first lattice results of the spectrum of exotic vector mesons extracted from the molecular and diquark-antidiquark operators, with quark fields (cq¯ q), and (cs¯ q)/(cq¯ s) re- c¯ c¯ c¯ spectively, 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 c¯ the spectrum of heavier exotic mesons with (cs¯ u)/(cu¯ s), (cs¯ d)/(cd¯ s), (cs¯ s), and (cc¯ c), as c¯ c¯ c¯ c¯ c¯ the first theoretical predictions from lattice QCD.
