SUMMARY
To measure the properties of the structure, an unbinned extended maximum_likelihood fit is performed to the - - - invariant mass distribution in the restricted Λ- cK π π 2 mass window of 3620 150 MeV=c (Fig 3). The sources of systematic uncertainty affecting the measurement of the Ξ-- mass include cc the momentum-scale calibration, the event selection, the unknown Ξ-- cc lifetime, the invariant mass fit model, and the uncertainty on . . .
