Measurement of the Time Reversal Asymmetry for the Decay $\bar{B}^{0}\rightarrow\Lambda\bar{p}\pi^{+}$ and Observation of the Decay $\bar{B}^{0}_{s}\rightarrow\Lambda\bar{p}K^{+}$ with the LHCb Experiment / Voss, Christian
This Analysis presents the measurement of the time reversal asymmetry in the decay $\bar{B}{}^{0}\rightarrow\Lambda\bar{p}\pi^{+}$ based on a triple product given by \begin{equation*} \mathcal{O} = \vec{s}_{\Lambda} \cdot \left( \vec{p}_\Lambda \times \vec{p}_\pi \right) \quad , \end{equation*} w [...]

Photon polarization in $B_s^0 \to \phi \gamma$ decays at the LHCb experiment / Ruiz Valls, Pablo
The Standard Model predicts a predominance of left handed photons emitted in the $b \to s\gamma$ interaction, due to the coupling of the $W$ boson to only left handed quarks [...]
