Search for flavour-changing neutral-current top quark decays to c-quark and Z boson using the ATLAS detector at the LHC / Marcoccia, Lorenzo
The main focus of this thesis is the search for the $t\rightarrow Z c$ process in the proton–proton collisions data collected by the ATLAS detector at the Large Hadron Collider located at CERN.\\ The flavour-changing neutral-current (FCNC) processes are forbidden at tree-level and highly suppres [...]
