The Search for $\Xi_b^0\rightarrow{J/\psi\Xi^-\pi^+}$ and $\Lambda_b^0\rightarrow{J/\psi\Xi^-K^+}$

This analysis aimed to measure the branching ratios of $\Lambda_b^0\rightarrow{J/\psi\Xi^-K^+}$ and $\Xi_b^0\rightarrow{J/\psi\Xi^-\pi^+}$ with the normalization channels, $\Lambda_b^0\rightarrow{J/\psi\Lambda}$ and $\Xi_b^-\rightarrow{J/\psi\Xi^-}$ respectively. This is done by comparing the simula...

description This analysis aimed to measure the branching ratios of $\Lambda_b^0\rightarrow{J/\psi\Xi^-K^+}$ and $\Xi_b^0\rightarrow{J/\psi\Xi^-\pi^+}$ with the normalization channels, $\Lambda_b^0\rightarrow{J/\psi\Lambda}$ and $\Xi_b^-\rightarrow{J/\psi\Xi^-}$ respectively. This is done by comparing the simulated decays to the LHCb data, performing several cuts, training a machine learning algorithm, and finally performing a massfit to find the branching ratios.
