We revisit the estimate of the charm particle contribution to the atmospheric neutrino flux that is expected to dominate at high energies because long-lived high-energy pions and kaons interact in the atmosphere before decaying into neutrinos. We focus on the production of forward charm particles which carry a large fraction of the momentum of the incident proton. In the case of strange particles, such a component is familiar from the abundant production of $K^{+} \Lambda$ pairs. These forward…

Intrinsic charm contribution to the prompt atmospheric neutrino flux
In this work we investigate the impact of intrinsic charm on the prompt atmospheric neutrino flux. The color dipole approach to heavy quark production is generalized to include the contribution of
Prompt neutrinos and intrinsic charm at SHiP
A bstractWe present a new evaluation of the far-forward neutrino plus antineutrino flux and number of events from charm hadron decays in a 400 GeV proton beam dump experiment like the Search for
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
Origin of the high-energy neutrino flux at IceCube
We discuss the spectrum of the different components in the astrophysical neutrino flux reaching the Earth, and the possible contribution of each component to the high-energy IceCube data. We show
Discovery and characterization of a diffuse astrophysical muon neutrino flux with the iceCube neutrino observatory
The IceCube Collaboration has previously discovered a flux of high-energy astrophysical neutrinos whose measurement is based on events with interaction vertices contained within the IceCube detector.
Charm production and prompt neutrino fluxes in beam dump and collider experiments
This dissertation deals with the neutrino fluxes that come from charm decays in hadronic collisions in beam dump and collider experiments. The specific focus is on the beam dump experiment SHiP
Impact of the inelastic proton–nucleus cross section on the prompt neutrino flux
The description of the inelastic proton -- nucleus cross section at very high energies is still an open question. The current theoretical uncertainty has direct impact on the predictions of the
Extracting the Energy-Dependent Neutrino-Nucleon Cross Section above 10 TeV Using IceCube Showers.
TLDR
Using six years of public IceCube High-Energy Starting Events, it is explicitly shown for the first time that the energy dependence of the cross section above 18 TeV agrees with the predicted softer-than-linear dependence, and reaffirm the absence of new physics that would make the crossSection rise sharply, up to a center-of-mass energy sqrt[s]≈1  TeV.
