Modular forms and hierarchical Yukawa couplings in heterotic Calabi-Yau compactifications

Abstract 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 modular forms in the context of heterotic string theory with standard embedding. We find that SL(2, ℤ) modular...
