    "abstract": "We propose a new interpolating field for S$_{11}$(1535) to determine its mass\nfrom QCD sum rules. In the nonrelativistic limit, this interpolating field\ndominantly reduces to two quarks in the s-wave state and one quark in the\np-wave state. An optimization procedure, which makes use of a duality relation,\nyields the interpolating field which overlaps strongly with the negative-parity\nbaryon and at the same time does not couple at all to the low lying\npositive-parity baryon. Using this interpolating field and applying the\nconventional QCD sum rule analysis, we find that the mass of S$_{11}$ is\nreasonably close to the experimentally known value, even though the precise\ndetermination depends on the poorly known quark-gluon condensate. Hence our\ninterpolating field can be used to investigate the spectral properties of\nS$_{11}$(1535).",
