Measurements of CP violation in B decays to charmless charged two-body final states at LHCb / Fazzini, Davide
This thesis presents the results obtained from the measurements of both the time-integrated (TI) $C\!P$ asymmetries of the $B^0 \rightarrow K^+ \pi^-$ and $B_s^0 \rightarrow \pi^+ K^-$ decays and the time-dependent (TD) $C\!P$ asymmetries of the $B^0 \rightarrow \pi^+ \pi^-$ and $B_s^0 \rightarrow [...]

Amplitude analysis and polarisation measurement of the $\Lambda^+_c$ baryon in $pK^-\pi^+$ final state for electromagnetic dipole moment experiment / Marangotto, Daniele
The first part of the thesis presents an experiment proposal for short-lived heavy baryon electromagnetic dipole moments measurement, exploiting spin precession of particles channeled in bent crystals, produced from fixed-target collisions of multi-TeV energy protons extracted from the main beam of [...]
