Three-Family Supersymmetric Pati-Salam Flux Models from Rigid D-Branes

Adeel Mansha, Mudassar Sabir, Tianjun Li +1

Intersecting D-brane model building often suffer from the unstabilized open-string moduli, leading to the unwanted massless adjoint scalars. In our previous work arXiv:2505.03664,…

Gauge dependence of scalar-induced gravitational waves from isocurvature perturbations: Analytical results

Arshad Ali, Yang Lei, Mudassar Sabir

We analytically study the gauge dependence of scalar-induced gravitational waves (SIGWs) sourced by primordial isocurvature perturbations during radiation domination (RD), working…

Three-family supersymmetric Pati-Salam models from intersecting D6-branes on rigid cycles

Adeel Mansha, Mudassar Sabir, Tianjun Li +1

Intersecting D6-brane models without discrete torsion typically suffer from unstabilized open string moduli, arising from D-brane positions and Wilson lines. These moduli generate…

Three family supersymmetric Pati-Salam model from rigid intersecting D6-branes

Adeel Mansha, Mudassar Sabir, Tianjun Li +1

We construct, for the first time, a three-family supersymmetric Pati-Salam model from rigid intersecting D6-branes on a factorizable $\mathbb{T}^6/(\mathbb{Z}_2\tim…

Fermion Masses and Mixings in String Theory with Dirac Neutrinos

Mudassar Sabir, Adeel Mansha, Tianjun Li +1

Analyzing the supersymmetric Pati-Salam landscape on a orientifold in IIA string theory, we have found only two models that accurat…

Fermion masses and mixings in the supersymmetric Pati-Salam landscape from Intersecting D6-Branes

Mudassar Sabir, Adeel Mansha, Tianjun Li +1

Recently, the complete landscape of three-family supersymmetric Pati-Salam models from intersecting D6-branes on a type IIA orienti…
