Impact of coherent scattering on relic neutrinos boosted by cosmic rays
Jiajie Zhang, Alexander Sandrock, Jiajun Liao +1
Ultra-high-energy cosmic rays (UHECR) scattering off the cosmic relic neutrino background have recently gained renewed interest in the literature. Current data suggest that (UHECR)…
Estimation of an Upper Limit on the Density of Relic Neutrinos in the Sun via the Solar B Neutrino Flux
Tim Ruhe, Alexander Sandrock
Relic neutrinos from the early universe are predicted to have a relatively large number density, but extremely low energies. Hence, the only possible interaction proceeds via neutr…
The effect of improved high-energy muon cross-sections
Jan Soedingrekso, Alexander Sandrock, Wolfgang Rhode
A precise simulation of muons with energies above a TeV is crucial for neutrino telescopes or cosmic ray experiments. To further increase the precision of these simulations, improv…
Search for steady point-like sources in the astrophysical muon neutrino flux with 8 years of IceCube data
IceCube Collaboration, M. G. Aartsen, M. Ackermann +325
The IceCube Collaboration has observed a high-energy astrophysical neutrino flux and recently found evidence for neutrino emission from the blazar TXS 0506+056. These results open…
Recent Improvements for the Lepton Propagator PROPOSAL
Mario Dunsch, Jan Soedingrekso, Alexander Sandrock +3
The lepton propagator PROPOSAL is a Monte-Carlo Simulation library written in C++, propagating high energy muons and other charged particles through large distances of media. In th…
Coulomb corrections to the bremsstrahlung and electron pair production cross section of high-energy muons on extended nuclei
Alexander Sandrock, Wolfgang Rhode
The energy reconstruction of high-energy muons depends on the energy loss characteristics. Accurate knowledge of the cross sections of the energy loss processes is necessary for pr…
Radiative corrections to the average bremsstrahlung energy loss of high-energy muons
Alexander Sandrock, Stanislav R. Kelner, Wolfgang Rhode
High-energy muons can travel large thicknesses of matter. For underground neutrino and cosmic ray detectors the energy loss of muons has to be known accurately for simulations. In…
Improved limits on dark matter annihilation in the Sun with the 79-string IceCube detector and implications for supersymmetry
IceCube Collaboration, M. G. Aartsen, K. Abraham +315
We present an improved event-level likelihood formalism for including neutrino telescope data in global fits to new physics. We derive limits on spin-dependent dark matter-proton s…
