Mass and width of strange baryon resonances in QCD sum rules
Abstract
The mass spectra of strange baryons in the octet family are investigated in a finite-energy QCD sum rule approach based on the Gauss-Weierstrass transform. The phenomenological form of the spectral function is saturated by the ground state and two of the lowest excited states, considered as having opposite parities. Treating the ground state parameters as known, the masses, widths and couplings to the interpolating fields are determined and compared to experiment.
