Lattice QCD determination of weak decays of B mesons
This thesis uses a variety of numerical and statistical techniques to perform high precision calculations in high energy physics using quantum field theory. It introduces the experimental motivation for the calculation of B meson form factors and includes a discussion of previous work. It then …

Analysis of B Meson Decays to Three Charged Pions
Decays of B mesons to three-body charmless final states probe the properties of the weak interaction through their dependence on the complex quark couplings in the CKM matrix. They also test dynamical models for hadronic B decays. Based on a sample of 772 million BB pairs collected by the Belle …

Hidden Sector: Three Different Ways
This thesis is a compilation of three projects that explore the consequences of different Hidden Sector models in various experimental fields. The first project proposes the Hidden Sector is populated by just one U(1) vector particle. It couples to the Standard Model through kinetic mixing and is …

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. …

Weak decays of beautiful pseudoscalar mesons with Lattice Quantum Chromodynamics
Weak decays of beautiful mesons can be used to probe the validity of our best model of particle physics: the Standard Model. In this thesis, I use specialised techniques to overcome practical challenges associated with the large mass of valence $b$ quarks to study a selection of decays of $B$ …

Measurement and Interpretation of Moments of the Combined Hadronic Mass and Energy Spectrum in Inclusive Semileptonic B-meson Decays
This thesis presents first measurements of moments of the hadronic n_X^2 distribution measured in inclusive semileptonic decays of B mesons to final states containing a charm quark, B->Xc l nu. The variable n_X^2 is a combination of the invariant mass of the charmed meson m_X, its energy in the …
