dc.description.abstract | ATLAS is one of the main general-purpose detector in LHC, it will be upgraded in 2023-2025 (which is called phase II). The major upgrade will be for the inner detector, it will be replaced by the new inner tracker (ITK). At that time the stage of high luminosity LHC (HL-LHC) will start with luminosity five times more than the luminosity in run 2 (nowadays), which creates a hope for a substantial advancement in the understanding of physics pheomena related to high-energy physics. The layout of ITK will cover a pseudorapidity (η) up to 4, while the current inner detector covers a pseudorapidity up to |η| = 2.5. In this thesis the track reconstruction efficiency (ϵ) and the fake rate as a function of different variables is studied in the ITK of ATLAS, including particles travel in the forward region with a values of 2.5 < |η| < 4. Tracking reconstruction efficiency (ϵ) as a function of several variables for two different samples is compared and decided which is better to use a modules of pixel size 50 × 50 µm2 or 25 × 100 µm2, this study is done with high pile-up, where the average number of proton-proton interactions per bunch crossing (µ) is around 200. The tracking reconstruction efficiency also is studied, as the value of µ is increased, this allows to study the roboustness of the track reconstruction efficiency with respect to high pile-up. | en_US |
