The IceCube Neutrino Observatory has observed highly energetic neutrinos in excess of the expected atmospheric neutrino background. It is intriguing to consider the possibility that such events are probing physics beyond the standard model. In this context, $\mathcal{O}$(PeV) dark matter particles decaying to neutrinos have been considered while dark matter annihilation has been dismissed invoking the unitarity bound as a limiting factor. However, the latter claim was done ignoring the…

Boosted dark matter in IceCube and at the galactic center

A bstractWe show that event excess observed by the IceCube collaboration at TeV-PeV energies, usually interpreted as evidence for astrophysical neutrinos, can be explained alternatively by the

Search for neutrinos from decaying dark matter with IceCube

Lower limits on the lifetime of dark matter particles are derived, obtaining the strongest constraint to date, excluding lifetimes shorter than 1028s at 90% CL for dark matter masses above 10TeV.

Coherent propagation of PeV neutrinos and the dip in the neutrino spectrum at IceCube

The energy spectrum of high-energy neutrinos reported by the IceCube Collaboration shows a dip between 400 TeV and 1 PeV. One intriguing explanation is that high-energy neutrinos scatter with the

Boosted dark matter and its implications for the features in IceCube HESE data

We study the implications of the premise that any new, relativistic, highly energetic neutral particle that interacts with quarks and gluons would create cascade-like events in the IceCube (IC)

Neutrinos from dark matter annihilation in the Milky Way satellites

The IceCube Neutrino Observatory under the South Pole observes the interaction of high-energy neutrinos within its cubic kilometre volume. This project aims to analyse these events in order to probe

Probing dark matter signals in neutrino telescopes through angular power spectrum

The hypothesis of two different components in the high-energy neutrino flux observed with IceCube has been proposed to solve the tension among different data-sets and to account for an excess of

Neutrinophilic Dark Matter in the epoch of IceCube and Fermi-LAT

The recent observation of the blazar TXS 0506+056 suggests the presence of a hard power-law component in the extraterrestrial TeV-PeV neutrino flux, in agreement with the IceCube analysis on the

Probing decaying heavy dark matter with the 4-year IceCube HESE data

After the first four years of data taking, the IceCube neutrino telescope has observed 54 high-energy starting events (HESE) with deposited energies between 20 TeV and 2 PeV . The background from

A consistent theory of decaying Dark Matter connecting IceCube to the Sesame Street

The high energy events observed at the IceCube Neutrino Observatory have triggered many investigations interpreting the highly energetic neutrinos detected as decay products of heavy unstable Dark

Heavy decaying dark matter at future neutrino radio telescopes

In the next decades, ultra-high-energy neutrinos in the EeV energy range will be potentially detected by next-generation neutrino telescopes. Although their primary goals are to observe cosmogenic



I and i

There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
