  In this article, we present the scalar-diquark-scalar-diquark-antiquark type
and scalar-diquark-axialvector-diquark-antiquark type pentaquark configurations
in the diquark model, and study the masses and pole residues of the
$J^P={\frac{1}{2}}^\pm$ hidden-charmed pentaquark states in details with the
QCD sum rules by extending our previous work on the $J^P={\frac{3}{2}}^-$ and
${\frac{5}{2}}^{+}$ hidden-charmed pentaquark states. We calculate the
contributions of the vacuum condensates up to dimension-10 in the operator
product expansion by constructing both the
scalar-diquark-scalar-diquark-antiquark type and
scalar-diquark-axialvector-diquark-antiquark type interpolating currents. The
present predictions of the masses can be confronted to the LHCb experimental
data in the future.
