Beyond the standard model searches in the top quark sectors at ATLAS and CMS / Chatterjee, Suman (Vienna, OAW) /ATLAS and CMS Collaborations
Searches for new physics are one of the most active fields of research at LHC. Due to its large mass, the top quark is predicted to have an enhanced coupling with the fields of new physics in several theoretical models. Multiple techniques are developed to probe new physics using the top quark as a tool in different phase space regions. [...]

Higgs rare decays at ATLAS and CMS / Dordevic, Milos (VINCA Inst. Nucl. Sci., Belgrade) /ATLAS and CMS Collaborations
More than a decade has passed since the start of the operation of the Large Hadron Collider at CERN and the discovery of the Higgs boson by the ATLAS and CMS Collaborations. The so far observed Higgs boson decay modes cover around 90$\%$ of the total Higgs boson width. [...]
