QCD Sum Rule for $\Lambda$(1405)

Nuclear Theory 2009-10-30 v1

Abstract

Motivated by the recently constructed interpolation field for S11_{11}(1535), we propose a new interpolating field for Λ\Lambda(1405). Using this current, we calculate the mass of Λ\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 Λ\Lambda(1405) to be very close to its experimental value.
