Abstract (inglese)

The estimation of the fraction of events in which an heavy quark is produced in the deeply inelastic electron–proton collisions is the measurement performed in the present analysis. The analysed data sample corresponds to about 130 pb-1 collected during the years 2004-2005 by the ZEUS detector, located in one of the interaction points of the HERA collider in Hamburg.
The measured percentages are directly related to the proton structure, formally encoded by the contribution of the heavy quarks to the structure functions F2.
The tagging of the events in which an heavy quark is produced is achieved by means of the Impact Parameter method. The correlation between the lifetime of the hadrons and the geometrical properties of the relative tracks makes possible
to pick out the heavy flavours production form the background.
This kind of ’topological’ method makes an extensive use of the silicon Micro Vertex Detector (MVD). This essential component of the tracking suite of the ZEUS detector has been the major upgrade realized in the second half of the ZEUS experiment data taking period. The achievement of the physical goal has strongly leaned on its performance and reliability, so a considerable part of the work consisted in feasibility, refinement and optimization studies.
