Search for vector-boson resonances decaying to a top quark and a bottom quark with the ATLAS experiment at LHC / Nibigira, Emery (Laboratoire de Physique de Clermont-Ferrand (LPC), Universite Clermont Auvergne, CNRS/IN2P3, Clermont-Ferrand, France)
A recent search for heavy resonances, namely $W'$ bosons, decaying to a top quark and a bottom quark with a lepton and missing transverse momentum plus jets in the final state is presented. [...]
