seems like someone read this statement thought it was funny and just plain made a story around it...look at all the things that match

The S=-2 di-hyperon sector has long been of interest because of an early prediction of a bound di-lambda (H particle) (R.L. Jaffe, Phys. Rev. Lett.\/) 38, 195 (1977).. However the R-matrix model, which includes long range hadronic effects as well as short range perturbative quark/gluon contributions, predicts a higher mass \Lambda\Lambda-\Xi N resonance at 2.35~GeV/c^2 (E.L. Lomon, AIP Conf. Proc.\/) 187, 8th Int. Symp. on High Energy Physics, K.J. Heller ed. (MN, 1988), p. 630 . Searches for the bound state have been negative (R.W. Stotzer et al., Phys. Rev. Lett.\/) 78, 3646 1997., leaving the possibility that the predicted resonance exists. In fact the exotic in question, a dimF=1, [q(1s_1/2)]^4 [s(1s_1/2)]^2 quark configuration, overlaps more strongly with the \Xi-N and \Sigma-\Sigma channels than with the \Lambda-\Lambda channel. Because of that and the fact that the exotic resonance is predicted to be above the \Xi-N threshold, the effect of the resonance should be substantial in \Xi-N scattering, a process observable in the laboratory using polarized or unpolarized nuclear targets. We are constructing a coupled channel R-matrix model for these channels, with meson exchange potentials at long range, so that specific predictions can be made for \Xi-N scattering. This will predict the observable effects of the \Lambda-\Lambda and \Sigma-\Sigma thresholds as well as that of the exotic resonance. Results will be described at the conference.
Xi-n =Xen
Lambda=lambda
and the guy who wrote it is from MIT?
or am i being to skeptical?
