Jet substructure at the Large Hadron Collider
In this thesis, we use the CMS Open Data to study the 2-prong substructure of jets. We use CMS's particle flow reconstruction algorithm to obtain jet constituents, which we then use to perform various jet substructure studies. After validating our basic kinematics and substructure results through a …

Precision Physics with W-bosons at the Large Hadron Collider
Weak bosons are by now a well-established and observed block of the elementary particles table, but the era of Precision Physics opens up new ways of utilising them in an attempt to uncover the mystery of physics beyond the Standard Model. Being central to what is called Electroweak Symmetry …

Light (anti)nuclei production with ALICE at the Large Hadron Collider
… objects. Heavy ion collisions produce not only hadrons (among which pions, kaons and protons are the most abundantly produced) but also composite and even fragile objects such as light nuclei (d, t, 3He, 4He) and light Λ-hypernuclei, along with their antiparticles. Their measured yields decrease …
