Ground state Meson masses in the Separation Geometry model
  In this paper the techniques of discretised QCD developed in physics/0109024 are are extended to a study of ground-state pseudo-scalar mesons involving higher generation quarks. The correspondence with empirical data is good with the exception of the charmed-bottom meson with the predicted value of 6.911GeV varying considerably from the empirical value of 6.4 GeV although it is still within two sigma and provides an avenue for further testing of the theory.
