Pentaquarks in QCD Sum Rule Approach

We estimate the mass of recently observed pentaquak staes - (1862) and +(1540) using two kinds of interpolating fields, containing two highly correlated diquarks, in the QCD sum rule approach. We obtained good agreement with the experimental value, using standard continuum threshold.
