Towards the field theory of the Standard Model on fractional D6-branes
on T6/Z6': Yukawa couplings and masses    [PDF]

Gabriele Honecker, Joris Vanhoof

We present the perturbative Yukawa couplings of the Standard Model on
fractional intersecting D6-branes on T6/Z6' and discuss two mechanisms of
creating mass terms for the vector-like particles in the matter spectrum,
through perturbative three-point couplings and through continuous D6-brane
displacements.
