Abstract

We study the states π1(1600) and π1(2015) in the QCD sum rule. We classify the tetraquark currents of the quantum numbers IGJPC=1-1-+, and find that the flavor structure (3  6 )(6  3 ) is preferred when using a diquarkantidiquark construction. By using both the SVZ and finite energy sum rules, we obtain a mass around 1.6 and 2.0 GeV, for the states with the quark contents qq and qs , respectively. We also study their decay patterns.
