    "abstract": "In the QCD sum rule approach we predict the $\\Lambda$ (1405) mass by choosing\nthe $\\pi^0\\Sigma^0$ multiquark interpolating field. It is found that the mass\nis about 1.419 GeV from $\\Pi_1 (q^2)$ sum rule which is more reliable than\n$\\Pi_q (q^2)$ sum rule, where $\\Pi_q (q^2)$ and $\\Pi_1 (q^2)$ are two invariant\nfunctions of the correlator $\\Pi (q^2)$. We also present the sum rules for the\n$K^+ p$ and the $\\pi^+\\Sigma^+$ multiquark states, and compare to those for the\n$\\pi^0\\Sigma^0$ multiquark state. The mass of the $\\Lambda$ (1600) can be also\nreproduced in our approach.",
