A search for Charge Parity (CP) violation is performed in $D^{0} \to K_{S}^{0} K \pi$ decays with the Energy Test (ET) method, an unbinned model independent statistical method pioneered by the University of Manchester [...]

Testing lepton flavour universality in $B^+\to K^+\pi^+\pi^-\ell^+\ell^-$ decays with LHCb / Celani, Sara
This PhD thesis aims at testing one of the fundamental properties of the Standard Model (SM) of particle physics: the lepton flavour universality (LFU), which states that $W$ and $Z$ bosons are equally coupled to the three lepton generations [...]

Measurement of the $B^{+}\rightarrow \rho^{0} \mu^{+} \nu_{\mu}$ differential branching fraction / Kirsebom, Veronica Soelund
The tension between different determinations of the CKM matrix element $|V_{ub}|$ using measurements of either exclusive or inclusive semileptonic decays represents a long-standing puzzle in flavour physics [...]

Measuring the CP violation Phase $\gamma$ in open charm B decays at LHCb / Sazak, Halime
This thesis presents the study of the measurement of the CKM angle $\gamma$ through two possible analysis at LHCb: first analysis, from the measurement of $B^0_s\rightarrow \tilde{D}^{(*)0}\phi$ decay, where the notation $\tilde{D}^{0}$ stands for either a $D^0$ or a $\overline{D}^0$ meson reconstru [...]
