Description
The existence of new states with spin one-half, i.e. extra-fermions, is a striking prediction of various classes of new
physics models.
Should one of these states be discovered during the 13 TeV runs of the LHC or at future high energy hadron colliders,
understanding its properties, such as their dominant coupling chirality or their width will be crucial in order to shed light on the
underlying model structure.
I will show how it is possible to characterise extra-fermions in different scenarios, and in the whole discovery range currently
accessible at the LHC and future colliders, thus effectively narrowing down the possible interpretations of a discovered state
in terms of new physics models.
