Query: Yukawa couplings and seesaw neutrino masses in noncommutative gauge
  theory   We consider Yukawa couplings in a theta-exact approach to noncommutative
gauge field theory and show that both Dirac and singlet Majorana neutrino mass
terms can be consistently accommodated. This shows that in fact the whole
neutrino-mass extended standard model on noncommutative spacetime can the
formulated in the new nonperturbative (in theta) approach which eliminates the
previous restriction of Seiberg-Witten map based theories to low-energy
phenomena. Spacetime noncommutativity induced couplings between neutrinos and
photons as well as Z-bosons appear quite naturally in the model. We derive
relevant Feynman rules for the type I seesaw mechanism.
