Symplectic modular symmetry in heterotic string vacua: flavor, CP, and R-symmetries

Abstract We examine a common origin of four-dimensional flavor, CP, and U(1) R symmetries in the context of heterotic string theory with standard embedding. We find that flavor and U(1) R symmetries are unified into the Sp(2h + 2, ℂ) modular symmetries of Calabi-Yau threefolds with h being the numbe...
