Constraining F-theory Model Building with QCD Axions
Keren Chen, Qinjian Lou, Yi-Nan Wang
In this paper, we investigate axion physics in 4D F-theory MSSM models. We derive the axion coupling term with QCD gauge fields and the axion potential from a top-down perspective,…

Vacuum Tunneling from Conifold Transitions in IIB
Xin Gao, Qinjian Lou, Yi-Nan Wang
We investigate the quantum tunneling process through a topology transition near a conifold singularity, in the setup of IIB CY3 orientifold compactification. We propose a novel met…

Massive Spectrum in F-theory and the Distance Conjecture
Keren Chen, Qinjian Lou, Yi-Nan Wang
We investigate the massive states in F-theory compactification models, including BPS string junctions stretching between parallel 7-branes and KK modes. We obtain analytical result…
