dc.description.abstractWe studied the weak three-body $B^0 \rightarrow K^0_s K^+ K^-$ decay at the LHCb experiment in the LHC at CERN. We validated the uncertainty on the CP observables using the current Dalitz plot analyses results from Run 1 and studied the uncertainties expected for Run 2 and Run 3. Using the simulation of the experimental conditions like the B-tagging (flavour of the $B^0$), the detector efficiencies and the number of events for the different data taking conditions, we have determined the expected precision of the CP-violating asymmetries of the flavour specific resonant modes, and we have shown evidence that analysis of the real data for Run 2 and Run 3 data taking periods could provide competitive $A_{cp}$ values compared with some of the actual measurements. Se estudió la desintegración a tres cuerpos $B^0 \rightarrow K^0_s K^+ K^-$ generada por el experimento LHCb (Large Hadron Collider beauty) en el LHC (Large Hadron Collider) del CERN (Conseil Européen pour la Recherche Nucléaire). Se validaron las incertidumbres en las contribuciones en los observables CP de las resonancias involucradas en los resultados actuales para la primera etapa de funcionamiento del experimento y se estudiaron los resultados esperados para las segunda y tercera etapas. Usando para ello la simulación de las condiciones experimentales como el sabor del $B^0$, las eficiencias del detector y el número de eventos esperados. Se determinó la precisión esperada en las medidas de la asimetría de violación CP para cada resonancia involucrada, y se mostró evidencia de que el análisis de los datos reales correspondientes a las segunda y tercera etapas del experimento podrían aportar medidas competitivas de $A_{cp}$, comparadas con los resultados actuales.eng
