Recent measurements of PeV energy neutrinos at IceCube and a 3.5 keV X-ray line in the spectra of several galaxies are both tantalizing signatures of new physics. This paper shows that one or both of these observations can be explained within an extended supersymmetric neutrino sector. Obtaining light active neutrino masses as well as phenomenologically interesting (keV-GeV) sterile neutrino masses without any unnaturally small parameters hints at a new symmetry in the neutrino sector that is…

Hints of a PeV Scale Supersymmetric Neutrino Sector: Neutrino Masses, Dark Matter, keV and PeV Anomalies

Neutrino masses and light (keV-GeV) sterile neutrinos can arise naturally via a modied, low energy seesaw mechanism if the right-handed neutrinos are charged under a new symmetry broken by a PeV

PeV scale supersymmetry breaking and the IceCube neutrino flux

A bstractThe observation of very high energy neutrino events at IceCube has grasped a lot of attention in the fields of both astrophysics and particle physics. It has been speculated that these high

X-Ray Lines from Dark Matter Annihilation at the keV Scale.

TLDR
This Letter introduces a novel model of fermionic dark matter χ with O(keV) mass, annihilating to a scalar state ϕ which in turn decays to photons, for instance via loops of heavy vectorlike fermions, and argues that it can easily avoid structure formation constraints on keV-scale dark matter.

IC at IC: IceCube can constrain the intrinsic charm of the proton

The discovery of extraterrestrial neutrinos in the $\sim$ 30 TeV -- PeV energy range by IceCube provides new constraints on high energy astrophysics. An important background to the signal are the

Exotic sterile neutrinos and pseudo-Goldstone phenomenology

A bstractWe study the phenomenology of a light (GeV scale) sterile neutrino sector and the pseudo-Goldstone boson (not the majoron) associated with a global symmetry in this sector that is broken at

Probing particle physics with IceCube

The IceCube observatory located at the South Pole is a cubic-kilometre optical Cherenkov telescope primarily designed for the detection of high-energy astrophysical neutrinos. IceCube became fully

Observation of the new emission line at ~3.5 keV in X-ray spectra of galaxies and galaxy clusters

The detection of an unidentified emission line in X-ray spectra of cosmic objects would be a 'smoking gun' signature for particle physics beyond the Standard Model. More than a decade of its

Freeze-in production of sterile neutrino dark matter in U(1)B−L model

With the advent of new and more sensitive direct detection experiments, scope for a thermal WIMP explanation of dark matter (DM) has become extremely constricted. The non-observation of thermal WIMP

Sterile Neutrino Dark Matter from Freeze-In

A sterile neutrino is a well-motivated and widely studied dark matter candidate. The most straightforward realization of sterile neutrino dark matter, through the Dodelson-Widrow mechanism, is now

I and i

TLDR
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.
