Majorana neutrino masses by D-brane instanton effects in magnetized orbifold models

Kouki Hoshiya, Shota Kikuchi, Tatsuo Kobayashi +3

We study Majorana neutrino masses induced by D-brane instanton effects in magnetized orbifold models. We classify possible cases, where neutrino masses can be induced. Three and fo…

Sharper estimates of Ohsawa--Takegoshi $L^{2}$ -extension theorem in higher dimensional case

Shota Kikuchi

Hosono obtained sharper estimates of the Ohsawa--Takegoshi $L^{2}$ -extention theorem by allowing the constant depending on the weight function for a domain in $C$ . In this a…

Classification of three generation models by orbifolding magnetized $T^{2} \times T^{2}$

Kouki Hoshiya, Shota Kikuchi, Tatsuo Kobayashi +2

We study orbifolding by the $Z_{2}^{(per)}$ permutaion of $T_{1}^{2} \times T_{2}^{2}$ with magnetic fluxes and its twisted orbifolds. We classify the possible three generation…

Modular symmetry by orbifolding magnetized $T^{2} \times T^{2}$ : realization of double cover of $Γ_{N}$

Shota Kikuchi, Tatsuo Kobayashi, Hajime Otsuka +2

We study the modular symmetry of zero-modes on $T_{1}^{2} \times T_{2}^{2}$ and orbifold compactifications with magnetic fluxes, $M_{1}, M_{2}$ , where modulus parameters are identified. This id…

Revisiting modular symmetry in magnetized torus and orbifold compactifications

Shota Kikuchi, Tatsuo Kobayashi, Shintaro Takada +2

We study the modular symmetry in $T^{2}$ and orbifold comfactifications with magnetic fluxes. There are $∣ M ∣$ zero-modes on $T^{2}$ with the magnetic flux $M$ . Their wavefunctions as w…
