Abstract.

Using the QCD sum rule method, we estimate the mass of the lowest strange mixed hybrid/three-quark baryon with IJ P = 0(1/2)- . We find the mass for a hybrid is approximately that of the \( \Lambda\)(1405) , whose nature has been a puzzle for many decades. Possible tests of this result are discussed.
