Zusammenfassung:	Treballs Finals de Grau de Física, Facultat de Física, Universitat de Barcelona, Any: 2014, Tutor: Hugo Ruiz Pérez A measurement of the mean life of the D0 meson is performed using real D0 -> K+ π- decay data collected at LHCb and selected according to the decay's speci c features. First, the selection algorithm is described. Then, the measurement of the mean life is optimized by changing the acceptance range of the data according to three variables involved in the selection. The value obtained for the mean life is compatible with the worldwide averaged value provided by the Particle Data Group. A measurement of the mean life of the D0 meson is performed using real D0 !
