With its enormous number of produced neutrinos, the LHC is a prime facility to study the behavior of high-energy neutrinos. This paper proposes a novel search strategy for identifying neutrino scattering via displaced appearing jets in the high granularity calorimeter (HGCAL) of the CMS endcap in the high luminosity run of the LHC. The study demonstrates in a cut-and-count based analysis how the enormous hadronic background can be reduced while keeping most of the neutrino signal. The paper serves as a proof-of-principle study to illustrate the feasibility of the first direct observation of high-energetic neutrinos coming from W decays.
