%0 Journal Article %T Stochastic GW backgrounds and Ground based detectors %A Massimo Giovannini %J Physics %D 2000 %I arXiv %R 10.1063/1.1363568 %X The interplay between different ground based detectors and stochastic backgrounds of relic GW is described. A simultaneous detection of GW in the kHz and in the MHz--GHz region can point towards a cosmological nature of the signal. The sensitivity of a pair of VIRGO detectors to string cosmological models is presented. The implications of microwave cavities for stochastic GW backgrounds are discussed. %U http://arxiv.org/abs/gr-qc/0009101v1
