Title: IceCube’s astrophysical neutrino energy spectrum from $C P T$ violation

Abstract

The six-year data set of high-energy starting events (HESEs) at IceCube indicates a spectrum of astrophysical neutrinos much softer than expected from the Fermi shock acceleration mechanism. On the other hand, IceCube’s up-going muon neutrino data set and Fermi-LAT’s gamma-ray spectrum point to an E^-2 neutrino spectrum. If the HESE data above 200 TeV are fit with the latter flux, an excess at lower energies ensues, which then suggests a multicomponent spectrum. We show that the HESE data set can be explained by a single E^-2 power-law neutrino flux from a muon-damped p γ source if neutrino interactions are modified by C P T violation. The low-energy excess is naturally explained by the pileup of events from superluminal neutrino decay, and there is no cutoff at high energies due to the contribution of subluminal antineutrinos. The best-fit scenario with C P T violation also predicts the observation of Glashow resonance events in the near future.

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

Journal Article Bhattacharya, Atri ; Esmaili, Arman ; Palomares-Ruiz, Sergio ; ... - Journal of Cosmology and Astroparticle Physics

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 atmospheric muons and neutrinos is expected to be of about 20 events, all below 100 TeV, thus pointing towards the astrophysical origin of about 8 events per year in that data set. However, their precise origin remains unknown. Here, we perform a detailed analysis of this event sample (considering simultaneously the energy, hemisphere and topology of the events) by assuming two contributions for the signal events: an isotropicmore »« less

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

Journal Article Bhattacharya, Atri ; Gandhi, Raj ; Gupta, Aritra ; ... - Journal of Cosmology and Astroparticle Physics

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) detector. Such events would be observationally indistinguishable from neutral current deep-inelastic (DIS) scattering events due to neutrinos. Consequently, one reason for deviations, breaks or excesses in the expected astrophysical power-law neutrino spectrum could be the flux of such a particle. Motivated by features in the recent 1347-day IceCube high energy starting event (HESE) data, we focus on particular boosted dark matter (χ) related realizations of this premise. Here, χ is assumedmore »« less

Angular correlation between IceCube high-energy starting events and starburst sources

Journal Article Moharana, Reetanjali ; Razzaque, Soebur - Journal of Cosmology and Astroparticle Physics

Starburst galaxies and star-forming regions in the Milkyway, with high rate of supernova activities, are candidate sources of high-energy neutrinos. Using a gamma-ray selected sample of these sources we perform statistical analysis of their angular correlation with the four-year sample of high-energy starting events (HESE), detected by the IceCube Neutrino Observatory. We find that the two samples (starburst galaxies and local star-forming regions) are correlated with cosmic neutrinos at ∼ (2–3)σ (pre-trial) significance level, when the full HESE sample with deposited energy ∼> 20 TeV is considered. However when we consider the HESE sample with deposited energy ∼> 60 TeV,more »« less

NEUTRINO ANALYSIS OF THE 2010 SEPTEMBER CRAB NEBULA FLARE AND TIME-INTEGRATED CONSTRAINTS ON NEUTRINO EMISSION FROM THE CRAB USING ICECUBE

Journal Article Abbasi, R ; Aguilar, J A ; Andeen, K ; ... - Astrophysical Journal

We present the results of a search for high-energy muon neutrinos with the IceCube detector in coincidence with the Crab Nebula flare reported on 2010 September by various experiments. Due to the unusual flaring state of the otherwise steady source we performed a prompt analysis of the 79-string configuration data to search for neutrinos that might be emitted along with the observed {gamma}-rays. We performed two different and complementary data selections of neutrino events in the time window of 10 days around the flare. One event selection is optimized for discovery of E{sup -2}{sub {nu}} neutrino spectrum typical of first-ordermore »« less

Multi-PeV Signals from a New Astrophysical Neutrino Flux beyond the Glashow Resonance

Journal Article Kistler, Matthew D. ; Laha, Ranjan - Physical Review Letters

The IceCube neutrino discovery was punctuated by three showers with E_ν ≈ 1–2 PeV. Interest is intense in possible fluxes at higher energies, though a deficit of E_ν ≈ 6 PeV Glashow resonance events implies a spectrum that is soft and/or cutoff below ~ few PeV. However, IceCube recently reported a through-going track depositing 2.6 ± 0.3 PeV. A muon depositing so much energy can imply E_νμ ≳ 10 PeV. Alternatively, we find a tau can deposit this much energy, requiring E_ντ ~ 10× higher. Here, we show that extending soft spectral fits from TeV-PeV data is unlikely to yieldmore »« less
