    "abstract": "In this work we report on a new QCD sum rule analysis to predict masses of\nthe excited baryon states (e.g. Sigma(1620) and Lambda(1405)) by using\nmultiquark interpolating fields ($(q\\bar{q})(qqq)$). For the Sigma(1620) we\nconsider the $\\bar{K}N$, $\\pi\\Sigma$, and $\\pi\\Lambda$ (I=1) multiquark\ninterpolating fields. The calculated mass from those multiquark states is about\n1.592 GeV. For the Lambda(1405) we first show the result using the\n  $\\pi^+\\Sigma^- + \\pi^0\\Sigma^0 + \\pi^-\\Sigma^+$ (I=0) multiquark\ninterpolating field, and compare the calculated mass to that of our previous\nresult using the $\\pi^0\\Sigma^0$ multiquark state. We then show that the mass\n1.405 GeV is well reproduced when using the $\\bar{K}N$ (I=0) multiquark state.\nThe uncertainties in our sum rules are also discussed.",
