ATLAS is one of the two main experiments at LHC with the purpose of investigating the microscopic properties of matter to address the most fundamental questions of particle physics. After the achievements of the first years of running, the potential reach for new discoveries and precise measurements at LHC is being extended by pushing further the energy and luminosity frontiers through three upgrades of the accelerator culminating in the High Luminosity LHC (HL-LHC). To fully profit from the increased luminosity, two main upgrades of the ATLAS inner detector are planned. The first upgrade was already completed at the beginning of 2015 with the insertion of the IBL, a fourth pixel layer located at just 3.2 cm from the beam line. In the second major upgrade, foreseen for 2024, the full inner detector will be replaced by a completely new inner tracker fully made of silicon devices to cope with the high particle density and the harsh radiation environment at the HL-LHC, which during its operational period will deliver 3000 fb-1, almost ten times the integrated luminosity of the full LHC program. This thesis addresses the study of new n+-in-p active edge pixel detectors by developing two novel doping profile analysis methods to study the radiation damage effects on the pixel detectors performance. These methods are the 3D sims imaging method and the TLM Method. TCAD simulation has been used to simulate the doping profiles, the electrical behavior and the radiation damage. Validating the simulation models with data have been done. Moreover, clean-room characterization, as well as testbeam measurement have been performed to test the different detector designs. In the second part of the thesis, I discuss the observation of the standard model Higgs boson bb decay mode using the data collected by ATLAS during the LHC Run2 at center-of-mass energy 13 TeV and an integrated luminosity 79.8 fb−1 of a proton-proton collision. I contributed specifically to the search of the standard model Higgs boson in VH(bb) production mode. In the VH(bb) analysis we don't have any channel that considers the tau leptons in the final state. I have performed a feasibility study to verify the gain of using the taus in the analysis. In addition, for the VH(bb) analysis I have worked on the multi-jet background estimation in the 1-lepton channel using the dijet-mass analysis method.

One of the most powerful machines to study particle physics is the Large Hadron Collider (LHC). Starting in 2024, it will be upgraded to the High Luminosity-LHC (HL-LHC) to deliver even more data to measure with high precision Standard Model (SM) physics processes, and to maximise the potential to discover new physics. Higher luminosity implies a higher radiation environment, which poses challenges to the detectors of the experiments. To deal with radiation damage, pile up, and needed read-out speed, ATLAS will replace its current tracking detector with the new Inner Tracker (ITk). The inne...

The integrated luminosity of the Large Hadron Collider (lhc), which is proportional to the number of particles colliding and thus data being collected, is planned to be increased by a factor of 5-7.5 compared to the design luminosity of the lhc by the end of the 2020s. This step is motivated by the potential to measure Standard Model physics processes especially in the top quark and Higgs sector with high precision and discover new physics. However, this upgrade to the High Luminosity-lhc will result in an increased particle density in the experiments, causing a higher hit occupancy in the ...

The High-Luminosity LHC (HL-LHC) upgrade of the CMS pixel detector will require the development of novel pixel sensors which can withstand the increase in instantaneous luminosity to L = 5 × 1034 cm-2s-1 and collect ~ 3000fb-1 of data. The innermost layer of the pixel detector will be exposed to doses of about 1016 neq/ cm2. Hence, new pixel sensors with improved radiation hardness need to be investigated. A variety of silicon materials (Float-zone, Magnetic Czochralski and Epitaxially grown silicon), with thicknesses from 50 [mu]m to 320 [mu]m in p-type and n-type substrates have been fabricated using single-sided processing. The effect of reducing the sensor active thickness to improve radiation hardness by using various techniques (deep diffusion, wafer thinning, or growing epitaxial silicon on a handle wafer) has been studied. Furthermore, the results for electrical characterization, charge collection efficiency, and position resolution of various n-on-p pixel sensors with different substrates and different pixel geometries (different bias dot gaps and pixel implant sizes) will be presented.
