Abstract:

In our initial exploratory study of the spectrum of spin-3/2 pentaquark states in quenched lattice QCD we indentified evidence of attraction between the nucleon and Kaon in the isoscalar, spin-3/2 even-parity channel, which could correspond to a physical resonance. The findings of our earlier study contrast those of a later lattice simulation of the same channel. In this report we review our findings in this channel. With a careful presentation of our lattice-data analysis, we resolve this discrepency and confirm our earlier results.
