AbstractThe lightcone QCD sum rules are employed to calculate the pi NN(1535) coupling g pi NN*. We study the two-point correlation function of two nucleon currents sandwiched between the vacuum and the pion state. The contribution from the excited states and the continuum is subtracted from the double Borel transform with respect to the nucleon and N(1535) momenta, p(1)(2), p(2)(2) = (p - q)(2). Our calculation shows that the pi NN(1535) coupling is strongly suppressed.
