The Large Hadron Collider (LHC) is currently the most powerful particle accelerator in the world,

delivering proton-proton collision in a lab environment at unprecedented energies. After the

discovery of the Higgs Boson in 2012, which was the latest missing piece of the Standard Model

(SM), the priority of the LHC program has now shifted towards the search for new physics. Some of

the most popular theories beyond the Standard Model predict the existence of Heavy Neutrinos in

order to address some of the most fundamental open questions in particle physics.

We propose a data analysis to search for the experimental signatures of Heavy Neutrinos with the

LHC data recorded by the CMS detector.

In this proposal we outline a number of original ideas, never pursued in CMS before, and new

analysis techniques that will substantially increase the experimental sensitivity for Heavy Neutrino

searches.
