Abstract: Mergers of two compact objects, like two neutron stars or a neutron star anda black hole, are the probable progenitor of short gamma-ray bursts. Theseevents are also promising sources of gravitational waves, that are currentlymotivating related searches by an international network of gravitational wavedetectors. Here we describe a search for gravitational waves from the in-spiralphase of two coalescing compact objects, in coincidence with short GRBsoccurred during during LIGO-s fifth science run and Virgo-s first science run.The search includes 22 GRBs for which data from more than one of the detectorsin the LIGO-Virgo network were available. No statistically significantgravitational-wave candidate has been found, and a parametric test shows noexcess of weak gravitational-wave signals in our sample of GRBs. The 90\%~C.L.median exclusion distance for GRBs in our sample is of 6.7 Mpc, under thehypothesis of a neutron star - black hole progenitor model.
