Observation of new $\Xi_c^0$ states decaying to $\Lambda_c^+K^-$, and development of the TORCH time-of-flight detector. / Gabriel, Emmy Pauline Maria
Using a data sample of proton-proton collisions at center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 5.6 fb$^{-1}$ collected by the LHCb experiment, the $\Lambda_c^+K^-$ mass spectrum is studied [...]

Understanding the impact of non-local contributions to $ \bar{B}^{0} \rightarrow \bar{K}^{ *0}μ^{+}μ^{-} $transitions / Pomery, Gabriela Johanna
The impact of the non-local contributions to $ \bar{B}^{0} \rightarrow \bar{K}^{ *0}\mu^{+}\mu^{-} $ decays has been assessed through creating a framework suitable to perform a five dimensional, unbinned, maximum likelihood fit to the data collected by the LHCb experiment [...]
