摘要：A comprehensive study of the cascade baryon spectrum using lattice QCD affords the prospect
of predicting the masses of states not yet discovered experimentally, and determining the spin
and parity of those states for which the quantum numbers are not yet known. The study of the
cascades, containing two strange quarks, is particularly attractive for lattice QCD in that the chiral
effects are reduced compared to states composed only of u/d quarks, and the states are typically
narrow. We report preliminary results for the cascade spectrum obtained by using anisotropic Nf
= 2 Wilson lattices with temporal lattice spacing 5.56 GeV−1.
