Analysis of the X(4350) as a scalar (c)over-barc and D(s)*(D)over-bar(s)* mixing state with QCD sum rules

PHYSICS LETTERS B

Abstract(summary):

In this Letter, we assume that the narrow structure X(4350) is a scalar (c) over barc-D(s)*(D) over bar (s)* mixing state, and study its mass using the QCD sum rules. The numerical result M(x) = (4.37 +/- 0.15) GeV is in good agreement with the experimental data, the X(4350) may be a scalar (c) over barc-D(s)*(D) over bar (s)* mixing state. Other possibility, such as a scalar (tensor) cs (c) over bar(s) over bar tetraquark state is not excluded. (C) 2010 Elsevier B.V. All rights reserved.
