Amplitude analysis for the measurement of the photon polarisation in $B \rightarrow K \pi \pi \gamma$ decays / Bellee, Violaine
This work proposes a method to measure the photon polarisation in $B^+ \rightarrow K^+ \pi^- \pi^+ \gamma$ decays and prepares the necessary elements for this measurement using the data sets collected by the LHCb experiment at CERN in $2011$, $2012$, $2016$ and $2017$ [...]
