This research aims to measure the mean lifetime for the B+ meson, a composition of a [up quark] and a [bottom antiquark] quark, by using experimental data obtained from LHCb. Making use of Monte Carlo (MC) generated data and simulated data, which includes the effects of a detector, we can study the effects over the data in order to obtain the physical parameters underlying the process. In order to find the mean lifetime [tau] of the B+ meson we will proceed by two different ways, and we will make use of the simulated Monte Carlo data to prove the validity of both methodologies.
