Heavy partners of the top quark are a common prediction of many models inwhich a new strongly-coupled sector is responsible for the breaking of the EWsymmetry. In this paper we investigate their experimental signature at the LHC,focusing on the particularly clean channel of same-sign dileptons.  We show that, thank to a strong interaction with the top quark which allowsthem to be singly produced at a sizable rate, the top partners will bediscovered at the LHC if their mass is below 1.5 TeV, higher masses beingpossible in particularly favorable (but plausible) situations. Being thepartners expected to be lighter in both the Higgsless and Composite-Higgsscenarios, the one of same-sign dileptons is found to be a very promisingchannel in which these models could be tested.  We also discuss several experimental signatures which would allow, after thediscovery of the excess, to uniquely attribute it to the top partnersproduction and to measure the relevant physical parameters, i.e. the toppartners masses and couplings. We believe that our results constitute a validstarting point for a more detailed experimental study.
