The estimation of neutrino fluxes produced by proton-proton collisions at $\sqrt{s}=14$ TeV of the LHC

TL;DR

This paper estimates the fluxes of neutrinos produced by charm and beauty decays in proton-proton collisions at 14 TeV at the LHC, proposing a neutrino detection setup that could observe around 150,000 events annually without disrupting LHC operations.

Contribution

It provides a detailed estimation of neutrino fluxes at the LHC and suggests a feasible detector configuration for neutrino observation during collider runs.

Findings

Approximately 150,000 charged current neutrino events per year can be observed.

Neutrino fluxes are significant enough for experimental detection at 300 meters from the interaction point.

The proposed setup operates parasitically, not interfering with LHC physics.

Abstract

Intense and collimated neutrino beams are produced by charm and beauty particle decays from proton-proton collisions at the LHC. A neutrino experiment would be run parasitically without interrupting the LHC physics program during the collider run. We estimate the neutrino fluxes from proton-proton collisions at $\sqrt{s}=14$ TeV of the LHC with the designed luminosity, $10^{34} \lumi$. By mounting about 200 tons of fiducial volume of a neutrino detector at 300 $\m$ away from the interaction point, about 150,000 of charged current neutrino events per year can be observable.
