Coupling Selection Rules in Heterotic Calabi-Yau Compactifications
Jun Dong, Tatsuo Kobayashi, Ryusei Nishida +2
We study coupling selection rules of chiral matter fields in heterotic string theory with standard embedding. These selection rules are determined by topological properties of Cala…
Modular forms and hierarchical Yukawa couplings in heterotic Calabi-Yau compactifications
Keiya Ishiguro, Tatsuo Kobayashi, Satsuki Nishimura +1
We study the modular symmetry in heterotic string theory on Calabi-Yau threefolds. In particular, we examine whether moduli-dependent holomorphic Yukawa couplings are described by…
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…
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…
