Testing Heavy Dark Matter Decay as the Origin of KM3-230213A
KM3NeT Collaboration, O. Adriani, J. A. Aguilar +287
This work explores the hypothesis that the ultra-high-energy neutrino event KM3-230213A originates from the decay of a heavy dark matter particle with a mass above PeV scale. The a…
Modelling Galactic neutrino emission: contributions from massive star clusters and interstellar cosmic rays
Stefano Menchiari, Silvia Celli, Vittoria Vecchiotti +3
The recent detection of Galactic neutrinos by the IceCube Observatory constitutes a remarkable achievement for neutrino astrophysics. By means of model dependent analyses based on…
Constraining gamma-ray burst parameters with the first ultra-high energy neutrino event KM3-230213A
KM3NeT Collaboration, O. Adriani, A. Albert +278
Context: The detection of the highest energy neutrino observed to date by KM3NeT, with an estimated energy of 220 PeV, opens up new possibilities for the study and identification o…
Probing hadronic gamma-ray and high-energy neutrino emission from Gaia DR2 star clusters
Alison M. W. Mitchell, Giovanni Morlino, Silvia Celli +2
Young and massive stellar clusters are a potential source of galactic cosmic rays due to at least two acceleration mechanisms. Collective stellar winds from massive stars form a wi…
Atmospheric neutrino constraints on Lorentz invariance violation with the first six detection units of KM3NeT/ORCA
KM3NeT Collaboration, O. Adriani, A. Albert +294
Lorentz invariance is a fundamental symmetry underlying both the Standard Model of particle physics and General Relativity. Testing its validity provides a direct means of searchin…
Search for an eV-scale sterile neutrino with the first six detection units of KM3NeT/ORCA
KM3NeT Collaboration, O. Adriani, A. Albert +285
The existence of an eV-scale sterile neutrino has been proposed to explain several anomalous experimental results obtained over the course of the past 25 years. The first search fo…
