Search for Neutrino Emission from GRB 221009A using the KM3NeT ARCA and ORCA detectors
arxiv(2024)
Abstract
Gamma-ray bursts are promising candidate sources of high-energy astrophysical
neutrinos. The recent GRB 221009A event, identified as the brightest gamma-ray
burst ever detected, provides a unique opportunity to investigate hadronic
emissions involving neutrinos. The KM3NeT undersea neutrino detectors
participated in the worldwide follow-up effort triggered by the event,
searching for neutrino events. In this letter, we summarize subsequent
searches, in a wide energy range from MeV up to a few PeVs. No neutrino events
are found in any of the searches performed. Upper limits on the neutrino
emission associated with GRB 221009A are computed.
