Implication

Phenomenological modeling reveals substantial theoretical uncertainties in far-forward tau neutrino fluxes at the LHC, indicating challenges in distinguishing sterile neutrino oscillations.

Key Points

To calculate the energy distributions of high-energy neutrinos produced from charm and bottom hadron decays in the far-forward region of the Large Hadron Collider and evaluate their sensitivity to sterile neutrino mixing.
Calculated heavy-flavor production cross-sections incorporating next-to-leading order QCD radiative corrections and phenomenological fragmentation functions.
Applied Gaussian transverse-momentum smearing to parton distribution functions to approximate non-perturbative intrinsic transverse-momentum effects and soft-gluon emissions, validating against LHCb double-differential cross-section data for charmed-strange mesons.
Simulated expected tau neutrino and antineutrino charged-current event rates in a 1 m long, 1 m radius lead detector 480 m from the interaction region under a 3+1 neutrino mixing framework.
Heavy-flavor production generates thousands of charged-current tau neutrino interactions in the proposed forward lead detector.
Large theoretical uncertainties in quantum chromodynamics parameters strongly impact the predicted far-forward neutrino flux distributions.
Theoretical uncertainties substantially limit the ability to detect tau neutrino oscillations into sterile neutrinos or distinguish a 3+1 scenario from standard three-flavor oscillations.
