摘要：

We have studied the mass spectra of the hidden-charm/bottom qc (q) over bar(c) over bar, sc (s) over bar(c) over bar and qb (q) over bar(b) over bar, sb (s) over bar(b) over bar tetraquark states with J(PC) = 0(++) and 2(++) in the framework of QCD sum rules. We construct ten scalar and four tensor interpolating currents in a systematic way and calculate the mass spectra for these tetraquark states. The X* (3860) may be either an isoscalar tetraquark state or chi(c0)(2P) If the X* (3860) is a tetraquark candidate, our results prefer the 0(++) option over the 2(++) one. The X* (4160) may be classified as either the scalar or tensor qc (q) over bar(c) over bar tetraquark state, while the X *(3915) favors a 0(++) qc (q) over bar(c) over bar or sc (s) over bar(c) over bar tetraquark assignment over the tensor one. The X *(4350) cannot be interpreted as a scsc tetraquark with either J(PC) = 0(++) 2(++).
