A Charged and Neutral Spin-$4$ Currents in the Grassmannian-like Coset Model
Abstract
By calculating the second order pole in the operator product expansion (OPE) of the charged spin- current with the neutral spin- current in the Grassmannian-like coset model, we determine the primary charged spin- current. Similarly, by computing the second order pole in the OPE of the neutral spin- current with itself, we obtain the primary neutral spin- current. We determine the OPE of the charged spin- current with the charged spin- current for generic parameters and the large (one of the parameters) limit is also obtained for this OPE. In particular, the above primary charged spin- current appears in the first order pole of this OPE for generic parameters. We also check that the above primary charged and neutral spin- currents occur at the second order pole in the OPE of the charged spin- current with itself for fixed parameters.
