A Search for Leptoquarks Coupling to $\tau$ Leptons and Bottom Quarks in Proton-Proton Collisions at the CMS Experiment / Neutelings, Izaak
Despite the many remarkable successes of the Standard Model (SM) of particle physics, there are both theoretical and experimental reasons that imply the SM is not the final and most fundamental theory of nature [...]

Data‐driven background modelling and trigger algorithms for compressed supersymmetry searches with the CMS experiment at the LHC / Zarucki, Mateusz
Supersymmetry (SUSY) is a highly motivated theory that can provide solutions to central issues and open questions of the standard model (SM) of particle physics [...]

Search for Dark Matter produced in association with Monotop in the fully leptonic channel in proton-proton collisions at 13 TeV with the Compact Muon Soleniod experiment / Uniyal, Rishabh
A search for dark matter has been performed using the monotop model, with the dark matter signature in the form of large missing energy, presence of a b-tagged jet and an isolated lepton (electron and muon) [...]

Measurement of inclusive and differential cross sections for single top quark production in association with a W boson in proton-proton collisions at $\sqrt{s}= 13 \text{ TeV}$ / Rodriguez Bouza, Victor
The main objective of this thesis is the study of the production of a top quark in association with a W boson (tW proccess) using proton-proton collision data collected by the CMS experiment at the LHC during Run 2 at a centre-of-mass energy of $\sqrt{s} = 13\text{ TeV}$ and corresponding to a total [...]

Study of WW Central Exclusive Production in the semileptonic channel with tagged protons at CMS detectorStudy of WW Central Exclusive Production in the semileptonic channel with tagged protons at CMS detector / Thiel, Mauricio
One of the most efficient approaches to look for physics Beyond the Standard Model is the use of the Effective Field Theory (EFT) to describe higher energy theoretical models at lower energies, like that of the LHC [...]
