   Sammanfattning : An evaluation of how sensitive some ATLAS searches for new physics are to a new beyond standard model (BSM) vector-like quark (VLQ) and a pseudo Nambu-Goldstone boson (pNGB) scalar. This was done by simulating a signal containing these new particles and making a recast of it onto existing verified ATLAS searches for new physics at center-of-mass (CM) energy of 13 TeV (Run 2) at the Large Hadron Collider (LHC).

3. 2. Studies of Hypothetical Vector-Like Quarks at the Large Hadron Collider

   Master-uppsats, Uppsala universitet/Högenergifysik

   Sammanfattning : A study for the search for vector-like quarks and a new pseudo Nambu-Goldstone boson(pNGB) scalar at the LHC running at $\sqrt{s} = 13$ TeV is presented. A model based on the composite Higgs model in which the Higgs boson emerges as a composite pNGB together with a new pNGB $\eta$ is considered. LÄS MER
