Search for a new light boson in exotic Higgs boson decays and the CMS muon spectrometer upgrade using GEM technology / Shah, Aashaq
The work presented in this thesis consists of a search for a new light boson in the exoticdecays of Higgs boson into the final state with a pair of bottom quarks (b¯b) and a pair ofmuons (µ− µ+ ), and muon endcap upgrade of the Compact Muon Solenoid (CMS) experimentusing Gas Electron Multiplier [...]

Vector Boson Fusion trigger and search for Higgs boson pair production at the LHC in the bbtautau channel with the CMS detector / Amendola, Chiara
This thesis describes a search for events with a pair of Higgs bosons (HH) in protonproton collisions at 13 TeV, provided by the Large Hadron Collider, with the CMS (Compact Muon Solenoid) experiment at CERN (Geneva).The study of the Higgs boson pair production allows its trilinear self-coupling (λ [...]

Unidentified Falling Objects in the Large Hadron Collider: Formation, Charging Mechanisms and Dynamics of Dust Particulates in a High Energy Proton Accelerator / Belanger, Philippe
Micrometer-sized dust particulates present in the LHC beam pipe are known to be causing a large number of sporadic beam loss events all around the LHC, some of which are large enough to provoke protection dumps or induce magnet quenches [...]

Search for compressed supersymmetry at the LHC in final states with one hadronic tau and one energetic jet / Segura Delgado, Manuel Alejandro
We present an experimental search of supersymmetry (SUSY) in compressed mass spectra scenarios with scalar taus ($\bar{\tau}$’s), using data from proton-proton (pp) collisions in the Large Hadron Collider, LHC, at CERN laboratory, at $\sqrt{s}$ = 13 TeV, collected by the CMS experiment in 2016 and [...]

Search for an extended scalar sector through the H$ \to$ ZA $\to$ $\ell^+ \ell^- b\bar{b}$ process in pp collisions at $\sqrt s=13$ TeV / Saggio, Alessia
The validity of the Standard Model (SM) of particle physics, has been remarkably proven by a large programme of experimental researches, culminating in the discovery of the Higgs boson in 2012 at CERN [...]

Search for Magnetic Monopoles in the CMS experiment at the Large Hadron Collider (LHC). / Mai M. El Sawy
A search for magnetic monopoles as an exotic long-lived particle, using a signature of a highly ionizing particle that deposits mostly of its energy in the Electromagnetic Calorimeter (ECAL) crystals, was performed with the CMS detector at the LHC using 33 $fb$$^{−1}$ of 13 $TeV$ proton-proton col [...]
