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…
