2018 PhD in High Energy Physics, University of Ghent, Belgium Thesis: The study of heavy Higgs (H/A) in the SM tt¯ final state using CMS data at 13 TeV (gg → A/H → tt¯→ SM particles). The analysis targets the heavy Higgs resonance as well as interference from the SM tt¯ with mass range from 400 to 750 GeV in steps of 100 GeV. Research and development of the CMS end-cap RPCs and designing its operating system in the GIF++ facility at CERN. CMS GEM detectors assembly for Phase-II upgrade at UGhent site. Advisor: Dr. Michael Tytgat, Prof. Dr. Didar Dobur

2013 Master in , Quaid-i-Azam University and Centre for Physics Islamabad, Pakistan Thesis: A Study of Top Quark pair using CMS data at 7 TeV. Calculation of cross sections, decay widths and BRs of SM and BSM Higgs using HIGLU and HDECAY programs. Advisor: Prof. Dr. Hafeez Hoorani

2010 Bachelor in Physics, Quaid-i-Azam University Islamabad, Pakistan Specialized in Physics Scientific Experience

2014-Present Physics Analysis: A search for a heavy Higgs boson decaying into a pair of top quarks was per- formed in the semileptonic final state using about 36 fb−1 of pp collision data collected by CMS in 2016. Masses ranging from 400 to 750 GeV are probed, and two pure CP states are considered. The interference with the QCD tt¯ produc- tion is found to play an important role, and it is taken into account explicitly. Upper limits on couplings of the hypothesized particle to top quarks were re- ported. In addition, exclusion limits in the (mA, tan β) plan has been calculated in the context of hMSSM model. 2018 GEM Detector Assembly: In view of the CMS experiment Phase-II upgrade, GEM technology has been selected as trigger and tracking system in the forward region of the Muon Spectrometer. The Ghent group is participating in the GEM assembly where 30 detectors will be assembled and tested.

2018 CMS RPC ageing studies: To study the possible ageing effects on the CMS RPC detector, I analyzed the HV scan data from 2016 to 2018 collected during different conditions. No major issue found during the Run-II and the framework is ready to be used in the future.

2017 NNLO Cross Section Calculation: To interpret the results of heavy Higgs in hMSSM, a study has been done for LO & NNLO cross sections calculation using SusHi and Top++ for signal and SM tt¯ respectively. The two programs are then cross checked with MADGRAPH and the final k-factors calculated as the ratio of LO to NNLO cross sections.

2017 RPC Muography for 2017B : A study has been done to find out RPC detectors with efficiency < 90% installed at CMS using 2017B data. In this study the real detector occupancy has been compared to the expected one. This study gave a good understanding of the RPCs detector geometry in the CMS detector and adjusting the RPC detector’s efficiency to it’s optimal level.

2014 - 2016 Detector Operation & Performance: A dedicated Detector Control System (DCS) has been developed using the WinCC-OA tool to control and monitor the CMS RPC detectors installed at the new CERN Gamma Irradiation Facility (GIF++) and to store the measured pa- rameters data. Preliminary efficiency studies that set the base performance measurements of CMS RPC for starting ageing studies are also presented.
