        Summary
        In particle physics determining the efficiency is an important step in measuring the invariant mass of a particle. This thesis presents the study of the efficiency for charged $\mathrm{D}^*$ mesons in pp collisions at 7 TeV at ALICE. Specifically this thesis looks at the difference in efficiency between charged $\mathrm{D}^*$ mesons being directly created and charged $\mathrm{D}^*$ mesons created in B meson decay. In the lower \pt region, the efficiency is higher for the \dstar from beauty compared to \dstar from charm. The difference mainly arrises in the vertexing step. We also look at 5 different cuts which differ in the reconstruction method, the effect of these 5 cuts on the ratio between the efficiency for \dstar from beauty and from charm is found to be small.
