Query: Noncommutative geometry, the Lorentzian Standard Model and its B-L
  extension   We explore the 1-loop renormalization group flow of two models coming from a
generalization of the Connes-Lott version of Noncommutative Geometry in
Lorentzian signature: the Noncommutative Standard Model and its B-L extension.
Both make predictions on coupling constants at high energy, but only the latter
is found to be compatible with the top quark and Higgs boson masses at the
electroweak scale. We took into account corrections introduced by threshold
effects and the relative positions of the Dirac and Majorana neutrino mass
matrices and found them to be important. Some effects of 2-loop corrections are
briefly discussed. The model is consistent with experiments only for a very
small part of its parameter space and is thus predictive. The masses of the
$Z'$ and B-L breaking scalar are found to be of the order $10^{14}$ GeV.
