Model-independent measurement of the CKM angle $\gamma$ in $B^\pm \to [h^+h^-\pi^+\pi^-] _Dh'^\pm (h = K , \pi)$ decays at LHCb and BESIII / Tat, Martin
This thesis describes two complementary analyses related to the four-body $D^0\to K^+K^-\pi^+\pi^-$ and $D^0\to\pi^+\pi^-\pi^+\pi^-$ decays, where the ultimate objective is to study $C\!P$ violation and measure the CKM angle $\gamma$ [...]

Search for $CP$ violation in semileptonic $B$ meson decays at the LHCb experiment / Dedu, Vlad-George
The measurement of CP-violating effects in $B$ meson semileptonic decays serves as a null test of the Standard Model (SM): any $CP$ violation would unambiguously imply the presence of New Physics (NP) in these decays [...]
