5312            Xib'-           Xibb'+          5.935           0.               0              0.5             ---             -1.
5314            Xib*-           Xibb*+          5.955           0.00165          0              1.5             ---             -1.

and generate

Xib*- ->  pi- { Xib0 -> ...

but the Xib* true mass is a dirac at 5.955. Not that it matters given our resolution, but still surprising.

I tried

minWidth : 0.0001

but that doesn't help.
