N2 - Very high energy emissions are believed to happen through particle acceleration in the jet originating from microquasars. This hypothesis was corroborated by the recent detections from the HAWC collaboration of very high energy gamma-ray events in the vicinity of SS433 and V4641Sgr microquasars. Through hadronic processes, neutrinos are produced together with these gamma-rays. We present results from a search of a neutrino signal from 13 microquasars which, according to multiwavelength observations, exhibited events of fast bulk ejecta in the context of outbursts characterized by strong X-Ray flares and spectral state transitions. This search is focused on X-Ray flaring and transitioning periods determined from RXTE/ASM, MAXI/GSC and Swift/BAT public data monitoring. The analysis is performed using data from the ANTARES neutrino telescope, which was dismantled during 2022 after 16 years of steady data acquisition, as well as with its successor KM3NeT, in construction in the Mediterranean Sea, with data from the KM3NeT/ORCA detector in its 6 lines configuration. No significant excess was found and upper limits on the neutrino fluxes are computed in the total observed flaring times and in specific spectral states.
