Description
Fractional D6-branes on toroidal orbifold backgrounds are known to be able to accommodate the particle spectrum and gauge group of the Standard Model, but up to now exact results for their low-energy effective action are missing.
In this talk, I will discuss how the conceptual ansatz for the field theory on the torus is generalised to those orbifold backgrounds on which the Standard Model spectrum can be realised on fractional branes.
