ANALYSIS OF THE 3/2± PENTAQUARK STATES IN THE DIQUARK MODEL WITH QCD SUM RULES

In this article, we construct the scalar-diquark-axialvector-diquark-antiquark-type interpolating currents, and study the masses and pole residues of the J(P) = 3/2(+/-) hidden-charmed pentaquark states with the QCD sum rules. In calculations, we use the formula mu = root M-P(2) - (2 M-c)(2) to determine the energy scales of the QCD spectral densities. We obtain the masses of the hidden-charm pentaquark states with the strangeness S = -1 and S = -2, which can be confronted with the experimental data in the future.
