Abstract
Gamma-ray bursts are promising candidate sources of high-energy astrophysicalneutrinos. The recent GRB 221009A event, identified as the brightest gamma-rayburst ever detected, provides a unique opportunity to investigate hadronicemissions involving neutrinos. The KM3NeT undersea neutrino detectorsparticipated in the worldwide follow-up effort triggered by the event,searching for neutrino events. In this letter, we summarize subsequentsearches, in a wide energy range from MeV up to a few PeVs. No neutrino eventsare found in any of the searches performed. Upper limits on the neutrinoemission associated with GRB 221009A are computed.File in questo prodotto:
