SUMMARY:Syed haider Abidi (University of Toronto) "Measurement of Higgs Boson Properties & ITk Detector Development"
DESCRIPTION:Abstract:\nDuring Run 1 of LHC\, the ATLAS and CMS collaboration firmly established the existence of a Higgs boson but detailed measurements were limited by statistical precision. With the larger Run 2 dataset\, we have measured the couplings and production cross-section of the Higgs boson using the H->ZZ->4l decay channel. The results improve upon the previous ones by more than a factor of 2. For the first time\, we also measure the differential cross-section within production modes and use it to place constraints on Beyond Standard Model scenarios.\nATLAS has an extensive detector upgrade plan to allow itself to collect and exploit the data delivered during HL-LHC. The upgrade of the current inner track with the all- silicon ITk is the largest project. At University of Toronto\, we have lead the Canadian effort to establish ITk strip module assembly. Collaborating with Celestica\, we have also established ASIC gluing and wire-bonding processes in industry. Additionally\, we are probing the impact of radiation damage to estimate the end-of-life performance of the ITk.\nBio:\nAs I have done my undergraduate training in Engineering Science\, I have been interested in bringing this prospective to physics research. As such I have been involved in many research projects\, ranging from condensed matter to accelerator development.\nSince 2013\, I have focused on measurements of Higgs boson properties using the ATLAS detector and ITk detector development. I have lead and been involved in numerous analyses using the H->ZZ->4l channel and analyses combining results from various other decay channels. Additionally I have led the development and investigation of ITk modules at University of Toronto. In the future\, I intend to continue pursuing both physics analyses and detector hardware.
