摘　　要：We studied the spectrum and rearrangement decays of S-wave cs■tetraquark states in a simplified quark model.The masses and widths were estimated by assuming that X(4140)is the lower 1^(++)cs■tetraquark.Comparing our results with experimental measurements,we found that X(3960),recently observed by LHCb,can be considered the lowest 0^(++)sc■tetraquark state and X0(4140)could be the second lowest 0^(++)cs■tetraquark.Predictions of ratios between partial widths for the involved tetraquarks are provided in this paper.We aim to identify more cs■tetraquarks with J^(PC)=1^(+-),0^(++),and 2^(++).
