Charm contribution to the atmospheric neutrino flux
@article{Halzen2016CharmCT, title={Charm contribution to the atmospheric neutrino flux}, author={Francis Halzen and Logan Wille}, journal={Physical Review D}, year={2016}, volume={94}, pages={014014} }
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…

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.
