We compute the angular pattern and the overlap reduction functions for the geodesic and nongeodesic response of the common mode of two interferometers interacting with a stochastic, massive scalar background. We also discuss the possible overlap between common and differential modes. We find that the cross-correlated response of two common modes to a nonrelativistic background may be higher than the response of two differential modes to the same background.

Abstract
We compute the angular pattern and the overlap reduction functions for the geodesic and nongeodesic response of the common mode of two interferometers interacting with a stochastic, massive scalar background. We also discuss the possible overlap between common and differential modes. We find that the cross-correlated response of two common modes to a nonrelativistic background may be higher than the response of two differential modes to the same background.File in questo prodotto:
