A bstract At colliders massive long-lived charged particles could be revealed through their
anomalously large ionisation energy loss dE/dx. In this paper we explore a class of …

Precise tracking is an indispensable tool for the study of many phenomena at new energy
frontier accessible with the CERN Large Hadron Collider (LHC). The tracking detectors of …

The ATLAS Pixel Detector is the innermost layer of the ATLAS tracking system and will
contribute significantly to the ATLAS track and vertex reconstruction. The detector consists of …

This thesis presents measurements of the production cross-sections of a $ 𝑍 $ boson in
association with $ 𝑏 $-jets and with $ 𝑐 $-jets. The measurements are performed using 139 …

The formulation of the Standard Model of particle physics (SM) is one of the greatest
scientific achievements of the 20th century. It is, however, incomplete (for example, it lacks a …

This thesis presents measurements of the production cross-sections of a Z boson in
association with b-jets and with c-jets. The measurements are performed using 139 fb-1 of …

After the discovery of the Higgs boson in 2012 by the ATLAS and CMS collaborations at the
Large Hadron Collider (LHC), precision measurements of the Higgs boson mass and …
