Abstract

We point out the possibility of detecting low-energy signals of moduli in superstring theory through neutrino oscillations. The idea is based on the characteristics that the couplings of moduli are different from matter to matter. We estimate the oscillation probability both in the base line and solar neutrino oscillations. In both cases, when there is at least one modulus of which the mass is less than or equal to 10−19 GeV, the interaction of the modulus significantly changes the conversion probability from one neutrino flavor to another.
