Despite its great success in describing microscopic phenomena, it is widely accepted that the Standard Model of particle physics is not a complete theory. In the past decades a large number of extensions of the Standard Model have been proposed. All of them predict the existence of new particles that might have played a crucial role in the high energy phase of the early Universe.At present we do not have a clear indication of the masses of these new particles and the energy scale of physics beyond the Standard Model. While the results of direct searches at the LHC direct-detection experiments have mainly confirmed the spectacular success of the Standard Model, there are intriguing discrepancies in the flavour sector which seem to form a coherent pattern. These anomalies consist of the observable P5' in B->K*mumu and the lepton universality breaking ratios R(K) and R(D(*)).The first measurement of P5' was part of my original SNF Professorship proposal and the analysis was completely developed and carried out at the University of Zurich (UZH). In addition, we had a leading role in confirming the P5' anomaly with the full dataset collected in RUN1 by LHCb. We are presently having a key role in measuring other observables that could confirm the R(K) deviation.This proposal is the Follow-up request of my SNF Professorship for two additional years. The main goal of the proposal is the conclusive understanding of the P5' and R(K) anomalies. This will require a set of new measurements, such as angular observables in the decay B0->K*ee. We will also develop a technique that will allow to Wilson coefficients and charm-loop contribution in B->K*ll directly from data. These measurements will conclusively test if these anomalies are due to new physics. Furthermore, searches for new sources of CP asymmetries in addition to that predicted by the Standard Model are among the main goals of current particle physics. In particular, studies involving decays of beauty baryons to purely hadronic final states became experimentally accessible only recently with the start of LHCb. First asymmetry measurements in multi-body charmless decays have been carried out by our group. These results motivated further studies in the area, which culminated with the first evidence of asymmetry between baryonic matter and antimatter in charmless decays, recently reported by LHCb (submitted to Nature Physics journal).This has an extraordinary impact to the field and further measurements with other multi-body beauty baryon decays are compulsory to confirm such observation. In this research proposal I will describe a set of measurements and phenomenological papers that will allow to make conclusive progress in understanding the Flavour Anomalies and will allow to confirm the first hint of CP violation in B-baryons observed by LHCb.
