String Quantum Symmetries and the SL(2,Z) Group

High Energy Physics - Theory 2009-10-22 v2

Abstract

We prove, using arguments relying only on the "special K\"ahler" structure of the moduli space of the Calabi-Yau three-fold, that in the case of one single modulus the quantum modular group of the string effective action corresponding to Calabi-Yau vacua can not be SL(2,ZZ{Z\kern -4.6pt Z}).
