    Description
The aim of this PhD thesis is to measure the lepton flavour universality (LFU)
in CMS at the Large Hadron Collider (LHC). LHC is a proton-proton collider
built in Geneve, where protons collide at about √s = 13 TeV, producing a great
amount of data used to study physical processes in detectors such as CMS.
In this presentation, I will present as motivation for my thesis a brief review of
some LFU tests in the decays of W: I will describe the discrepancy found by
LEP, and the following studies made by ATLAS and CMS. I will then propose
my strategy to reduce the uncertainty and produce an high precision LFU test
between τ and μ at CMS, exploiting also the new statistics to be provided by
Run3.
