Computation of D-brane instanton induced superpotential couplings: Majorana masses from string theory

Show other versions (1)

We perform a detailed conformal field theory analysis of D2-brane instanton effects in four-dimensional type IIA string vacua with intersecting D6-branes. In particular, we explicitly compute instanton induced fermion two-point couplings which play the role of perturbatively forbidden Majorana mass...
