Abstract

We take the viewpoint that X (1576) is the tetraquark state which consists of a scalar diquark and an anti-scalar-diquark in relative P -wave, and calculate its mass in the framework of the QCD sum rule approach. The numerical value of the mass m X = (1.66±0.14) GeV is consistent with the experimental data. There might be some tetraquark components in the vector meson X (1576).
