摘要：
Motivated by the recently constructed interpolation field for S-11(1535), we propose a new interpolating field for Lambda<1405). Using this current, we calculate the mass of Lambda(1405) based on the conventional QCD sum rule analysis. By calculating the Wilson coefficients up to dimension 8 operators and taking into account the mass corrections from s-quark, we find the calculated mass of Lambda(1405) to be very close to its experimental value.
