摘要：

We investigate the mass spectrum of 1(+) exotic mesons with quark content (cs (c) over bar(p) over bar)/(cq (c) over bar(s) over bar), using molecular and diquark-antidiquark operators, in quenched lattice QCD with exact chiral symmetry. For the molecular operator {((q) over bar gamma(i)c)((c) over bar gamma(5)s)-((c) over bar gamma(i)s)((q) over bar gamma(5)c)} and the diquark-antidiquark operator {[q(T)C gamma(i)c][(s) over barC gamma(5)(c) over bar (T)]-[q(T)C gamma(5)c][(s) over barC gamma(T)(i)(c) over bar (T)]}, both detect a 1(+) resonance with mass around 4010 +/- 50 MeV in the limit m(q)-> m(u,d).
