Autoencoder-Driven Clustering of Intersecting D-brane Models via Tadpole Charge
Keiya Ishiguro, Satsuki Nishimura, Hajime Otsuka
We study the well-known type IIA intersecting D-brane models on the orientifold via a machine-learning approach. We apply several autoenco…
Flux Landscape with Enhanced Symmetry Not on Elliptic Points
Keiya Ishiguro, Takafumi Kai, Tatsuo Kobayashi +1
We study structures of solutions for SUSY Minkowski F-term equations on two toroidal orientifolds with . Following our previous study \cite{Ishiguro:2020tmo}, with fi…
Novel moduli space in modular flavor models : a case study for modular seesaw model with hidden gauge symmetry
Keiya Ishiguro, Takaaki Nomura, Hiroshi Okada +2
We study flavor phenomenologies in a basis of a double covering of modular group with a hidden symmetry, in which we work on regions at nearby two fixed points and th…
Modular flavor models with positive modular weights: a new lepton model building
Tatsuo Kobayashi, Takaaki Nomura, Hiroshi Okada +1
We propose an interesting assignment of positive modular wights for fields in a modular non-Abelian discrete flavor symmetry. By this assignment, we can construct inverse seesaw an…
Texture zeros realization in a three-loop radiative neutrino mass model from modular symmetry
Takaaki Nomura, Hiroshi Okada, Hajime Otsuka
We derive verifiable two-zero textures in the framework of a three-loop induced neutrino mass model applying a modular symmetry for the lepton sector. Interestingly, the neut…
Upper bound on the Atiyah-Singer index from tadpole cancellation
Keiya Ishiguro, Takafumi Kai, Satsuki Nishimura +2
We propose an upper bound on the Atiyah-Singer index in the effective action of string theory. For and heterotic string theories on smooth Calabi-Y…
Flavor, CP and Metaplectic Modular Symmetries in Type IIB Chiral Flux Vacua
Takafumi Kai, Keiya Ishiguro, Hiroshi Okada +1
We examine symmetries of chiral four-dimensional vacua of Type IIB flux compactifications with vanishing superpotential . We find that the supersymmetric MSSM-lik…
Exploring the flavor structure of quarks and leptons with reinforcement learning
Satsuki Nishimura, Coh Miyao, Hajime Otsuka
We propose a method to explore the flavor structure of quarks and leptons with reinforcement learning. As a concrete model, we utilize a basic value-based algorithm for models with…
Moduli inflation from modular flavor symmetries
Yoshihiko Abe, Tetsutaro Higaki, Fumiya Kaneko +2
We study slow-roll inflation model controlled by the modular flavor symmetry. In the model, the modulus field plays a role of inflaton and the introduction of the stabilizer field…
Remark on modular weights in low-energy effective field theory from type II string theory
Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu +3
We revisit the modular weights in type IIB magnetized D-brane models. The simple analysis of wave function shows that the four-dimensional matter fields have the modular weight -1/…
