Description
The classical part of Yukawa couplings from D6-branes is computed by summing over worldsheet instantons. On non-factorisable tori the worldsheet instantons obey selection rules, which depend on the underlying lattice of the torus. Quantum corrections to the couplings are obtained by T-dualizing the setup and computing the overlapping wavefunctions of three chiral matter fields.
