The second period of datataking at the Large Hadron Collider (LHC) has provided a large
dataset of proton–proton collisions that is unprecedented in terms of its centre-of-mass …

The identification of prompt and isolated muons, as well as muons from heavy-flavour
hadron decays, is an important task. We developed two multivariate techniques to provide …

We study the phenomenology of a particular leptoquark extension of the Standard Model
(SM), namely the doublet-singlet scalar leptoquark extension of the SM (DSL-SM). Besides …

Leptoquarks (LQ s) are hypothetical particles that appear in various extensions of the
Standard Model (SM), that can explain observed differences between SM theory predictions …

Machine learning offers an exciting opportunity to improve the calibration of nearly all
reconstructed objects in high-energy physics detectors. However, machine learning …

The production of heavy neutral mass resonances,\(\text {Z}^{\prime}\), has been widely
studied theoretically and experimentally. Although the nature, mass, couplings, and …

Within the context of studies for novel measurement solutions for future particle physics
experiments, we developed a performant kNN-based regressor to infer the energy of highly …

A search for long-lived particles (LLPs) decaying in the CMS muon detectors is presented. A
data sample of proton-proton collisions at s= 13 TeV corresponding to an integrated …

We present a phenomenology study probing pair production of supersymmetric charginos
and neutralinos (" electroweakinos") with the vector boson fusion (VBF) topology in proton …

This thesis presents the search for heavy neutral Higgs bosons, produced in associationwith
b-quarks and decaying into a b-quark pair in proton-proton collisions at a centre-ofmass …
