[en] We derive a conservative coincidence time window for joint searches of gravitational-wave (GW) transients and high-energy neutrinos (HENs, with energies ≥100 GeV), emitted by gamma-ray bursts (GRBs). The last are among the most interesting astrophysical sources for coincident detections with current and near-future detectors. We take into account a broad range of emission mechanisms. We take the upper limit of GRB durations as the 95% quantile of the T₉₀'s of GRBs observed by BATSE, obtaining a GRB duration upper limit of ∼ 150 s. Using published results on high-energy (≥100 MeV) photon light curves for 8 GRBs detected by Fermi LAT, we verify that most high-energy photons are expected to be observed within the first ∼ 150 s of the GRB. Taking into account the breakout-time of the relativistic jet produced by the central engine, we allow GW and HEN emission to begin up to 100 s before the onset of observable gamma photon production. Using published precursor time differences, we calculate a time upper bound for precursor activity, obtaining that 95% of precursors occur within ∼ 250 s prior to the onset of the GRB. Taking the above different processes into account, we arrive at a time window of t_HEN - t_GW is in the range of [500 s,+500 s]. Considering the above processes, an upper bound can also be determined for the expected time window of GW and/or HEN signals coincident with a detected GRB, t_GW - t_GRB ≅ t_HEN - t_GRB is in the range of [350 s,+150 s]. These upper bounds can be used to limit the coincidence time window in multi-messenger searches, as well as aiding the interpretation of the times of arrival of measured signals. (authors)
