New W-prime signals at the LHC
arXiv:1404.5558 · doi:10.1103/PhysRevD.89.095027
Abstract
We study the phenomenology in composite Higgs/ warped extra dimensional models focusing on the effect of fermionic resonances at 1 TeV. After deriving the existing bounds from the current LHC-8 analyses, we highlight the most promising signatures for discovery at the 14 TeV LHC. We find in particular very promising the study of decay modes into vector-like top partners, specifically the decay into a doublet of custodian heavy fermions, , and the decay into a heavy fermion plus a Standard Model quark. We perform a detailed parton level analysis of the channel in the same-sign dilepton final state, finding that it is a very promising signature to test the region at high mass, TeV, and of the mode, that is one of the best channels to test the intermediate mass region and that, already with the LHC-8 data, could extend the present exclusion bounds.
