Search for the lepton flavour violating decays B0 -> emu and B0s -> emu with LHCb Run 2 data

Sebastian Schulte

A large variety of new physics models suggest that the rates for lepton flavour violating bb-hadron decays may be much higher than predicted in the Standard Model, which leads to a high interest in the search for such decays. This thesis presents the sear ...

Amplitude analysis for the measurement of the photon polarisation in B rightarrow K pi pi gamma decays

Violaine Bellée

This work proposes a method to measure the photon polarisation in B+→K+π−π+γB^+ \rightarrow K^+ \pi^- \pi^+ \gamma decays and prepares the necessary elements for this measurement using the data sets collected by the LHCb experiment at CERN in 20112011, 20122012, $2016 ...
