Abstract
In this Letter, we assume that the narrow structure X(4350) is a scalar c¯c-Ds*D¯s* mixing state, and study its mass using the QCD sum rules. The numerical result MX=(4.37±0.15) GeV is in good agreement with the experimental data, the X(4350) may be a scalar c¯c-Ds*D¯s* mixing state. Other possibility, such as a scalar (tensor) csc¯s¯ tetraquark state is not excluded.
