Light dark matter with AURIGA detector

The search power of the cryogenic resonant-mass AURIGA detector for a new scalar field called moduli, has been explored in the present work. Moduli are predicted by String Theory and may have significant contribution to the Dark Matter in our universe. Interactions of moduli with ordinary matter causes the oscillation of solids with a frequency equal to the moduli mass. Thus, the AURIGA detector could detect moduli as a resonance within its bandwidth. In the following, the signal characteristics have been studied through simulation and a projection of the sensitivity has been obtained.
