D-Instanton Generated Dirac Neutrino Masses

Mirjam Cvetic, Paul Langacker

We present a stringy mechanism to generate Dirac neutrino masses by D-instantons in an experimentally relevant mass scale without fine-tuning. Within Type IIA string theory with in…

New Grand Unified Models with Intersecting D6-branes, Neutrino Masses, and Flipped SU(5)

Mirjam Cvetic, Paul Langacker

We construct new supersymmetric SU(5) Grand Unified Models based on Z4 x Z2 orientifolds with intersecting D6-branes. Unlike constructions based on Z2 x Z2 orientifolds, the orbifo…
