Mass-matching in Higgsless
Abstract
Modern extra-dimensional Higgsless scenarios rely on a mass-matching between fermionic and bosonic KK resonances to evade constraints from precision electroweak measurements. After analyzing all of the Tevatron and LEP bounds on these so-called Cured Higgsless scenarios, we study their LHC signatures and explore how to identify the mass-matching mechanism, the key to their viability. We find singly and pair produced fermionic resonances show up as clean signals with 2 or 4 leptons and 2 hard jets, while neutral and charged bosonic resonances are visible in the dilepton and leptonic W ± Z 0 channels, respectively. A measurement of the resonance masses from these channels shows the matching necessary to achieve S ≃ 0. Moreover, a large single production of KKfermion resonances is a clear indication of compositeness of SM quarks. Discovery reach is below 10 fb-1 of luminosity for resonances in the 700 GeV range.
