1. Calibration of b-tagging and search for Dark Matter : Calibration of b-tagging efficiency and search for Dark Matter production in association with heavy flavour quarks with the ATLAS experiment
Sammanfattning : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS and the CMS are the two multipurpose particle detectors at the LHC, designed to cover a wide range of physics measurements. LÄS MER
2. Calibration of b-tagging efficiency and search for Dark Matter production in association with heavy flavour quarks with the ATLAS experiment
Sammanfattning : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS detector is a general-purpose particle detector at the LHC, designed to cover a wide range of physics measurements. LÄS MER
3. The Beauty in Broken Symmetries : b-jet identification and searches for Supersymmetry, Dark Matter and multi-Higgs boson production with the ATLAS experiment
Sammanfattning : The Large Hadron Collider is the largest and most powerful accelerator in the world. Proton bunches are accelerated to 6.5 TeV inside the LHC ring in opposite directions and are then collided at four different points around the ring with an energy of 13 TeV. LÄS MER
4. The decay of beauty quark to τ lepton and neutrino in the DELPHI experiment at LEP
Sammanfattning : Using 3.5 millions hadronic Z0 events collected during the LEP1 period at the DELPHI detector, the decays of b quarks to tvt have been searched for in both the inclusive and exclusive decay modes. The analysis technique is based on b-tagging, missing energy and identifications of t products. LÄS MER
5. Measurements of the Top Quark Pair Production Cross Section and an Estimate of the DØ Silicon Detector Lifetime
Sammanfattning : This thesis presents two measurements of the top quark pair production cross section at sqrt{s} = 1.96 TeV using data from the DØ experiment. Both measurements are performed in the dilepton final state and make use of secondary vertex b-tagging. LÄS MER
