1. 1. Reconstruction of challenging signatures characteristic to new physics beyond the Standard Model

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

   Författare :Timmy Lindgren; [2020]
   Nyckelord :Reconstruction; Identification; photon-jets; ATLAS;

   Sammanfattning : A study of photon-jets and their identification variables computed in the electromagnetic calorimeter of an in-house, ATLAS-like, detector model developed at Uppsala University for full-simulations is presented. The signal, which is based on the Composite Higgs Model, considers the pair production of vector-like top quarks, denoted t', with the successive decays t' to S and a Standard Model top quark and S to two photons, where S is a new pseudo-scalar boson.

3. 2. Derivation of a transfer function to estimate the Z(vv)+jets background from photon+jets in a search for dark matter at the ATLAS detector

   Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Emelie Olsson; [2019]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : It has for long been known that dark matter must exist in our universe. Despite massive efforts to detect dark matter, its constituents remain a mystery. One strategy to unveil this mystery is to produce dark matter by colliding Standard Model particles. LÄS MER
