Contribution to the Analysis of the $B^{+}_{c} \to K^{+}K^{-}\pi^{+}$ decay in the LHCb Experiment

The studies of the $B^{+}_{c}$ meson's decays to final states containing $K^{+}K^{-}\pi^{+}$, occurring through either direct annihilation diagrams or diagrams containing an intermediate $D^{0}$ meson, are potentially useful to probe Standard Model predictions. However, very few measurements regarding the $B^{+}_{c}$ meson have been performed, due to its low probability of being produced in particle accelerators. A measurement of these decays is only possible with the collision energies and the unprecedented amount of statistical data collected at the LHC. This dissertation details the steps in the $B^{+}_{c} \to K^{+}K^{-}\pi^{+}$ analysis that attempts to perform a measurement of the $B^{+}_{c}$ signal, using data collected by the LHCb detector from $2010$ to $2012$. The event selection is completed and the full fit model is determined, in preparation for a final measurement.
