PROBING THE HIGGS BOSON WITH THE ATLAS DETECTOR: PRECISION MEASUREMENTS OF THE MASS AND SEARCH FOR RARE DECAYS TO A LOW-MASS DILEPTON SYSTEM AND A PHOTON IN PROTON-PROTON COLLISIONS AT THE LHC
… the Higgs boson mass $m_H$, and the search for a rare SM decay mode not yet observed, namely the decay into a low-mass dilepton system and a photon. \noindent The first analysis presents a precision measurement of the Higgs boson mass in the diphoton decay channel, $H \rightarrow \gamma\gamma$, …

Digital Signal Processing for segmented HPGe Detectors, Preprocessing Algorithms and Pulse Shape Analysis
… detectors, build for the efficient detection of rare decays in nuclear reactions of radioactive ion beams. MINIBALL was the first spectrometer equipped with digital electronics. Pulse shape analysis algorithms to determine the interaction position of gamm-rays were implemented on a Digital Signal …

Studies of rare B-meson decays to muons at the LHCb experiment
In this dissertation, very rare decays of B-mesons to purely muonic final states, both dimuon and four-muon, are studied at the LHCb experiment using data recorded during the first and second data-taking periods of the Large Hadron Collider, spanning the years 2011–2012 and 2015–2018, respectively. …

Determination of the X(3872) Meson Quantum Numbers
… of Charge Parity (CP) violation parameters and rare decays of the beauty and charm hadrons. The detector was successfully operated at a center-of-mass energy of 7 TeV in 2010 and 2011 and at 8 TeV in 2012. Over 3 fb-1 of data has been collected by the LHCb. The LHCb experiment is also well …

Beauty meson to double open charm decays with the LHCb detector
Measurements of beauty meson to double open charm decays are presented. These measurements use data collected in proton-proton collisions by the LHCb detector at the Large Hadron Collider (LHC) between 2011 and 2018. Firstly a search for sixteen rare decays of the $B_c^+$ meson to two charm mesons …

Measurements of $B \to \mu^+ \mu^-$ decays using the LHCb experiment
This dissertation documents a study of very rare $B$-meson decays at the LHCb experiment, using data taken during the first experiment run of the Large Hadron Collider (LHC) and during the second experiment run until September 2016. The LHCb experiment was designed to test the Standard Model of …

Observation of upsilon suppression, search for long-lived particles, and observation of B0s → micro + micro-- at the LHC with the CMS experiment
… pair of long-lived neutral bosons, each of which decays to dileptons. In the second, events contain a pair of squarks that each decay to a long-lived neutralino, each of which in turn decays to dileptons and a neutrino. We performed the search with the CMS tracker and muon system separately and …
