Flavor structure of magnetized blow-up models
Tatsuo Kobayashi, Hajime Otsuka, Hikaru Uchida
We discuss the flavor structure in a resolutions of magnetized orbifold models. The flavor structure of Yukawa couplings among chiral zero-modes is sensitive to…
F-theory Flux Vacua and Attractor Equations
Yoshinori Honma, Hajime Otsuka
We examine the vacuum structure of 4D effective theories of moduli fields in spacetime compactifications with quantized background fluxes. Imposing the no-scale structure for the v…
Unitary matrix with a Penner-like potential also yields N_f=2
Shun'ya Mizoguchi, Hajime Otsuka, Hitomi Tashiro
It has been known for some time that a hermitian matrix model with a Penner-like potential yields as its large-N free energy the prepotential of N=2 N_f=2 SU(2) SUSY gauge theory.…
Wavefunctions and Yukawa Couplings on Resolutions of Orbifolds
Tatsuo Kobayashi, Hajime Otsuka, Hikaru Uchida
We propose matter wavefunctions on resolutions of singularities with constant magnetic fluxes. In the blow-down limit, the obtained wavefunctions of chiral zero-…
Heterotic Stringy Corrections to Metrics of Toroidal Orbifolds and Their Resolutions
Pompey Leung, Hajime Otsuka
We explicitly analyse corrections to heterotic supergravity on toroidal orbifolds and their resolutions, which play important roles in string phenomenology as well as modul…
