Abstract
We study the phenomenology of vector resonances in the context of natural composite Higgs models A mild hierarchy between the fermionic partners and the vector resonances can be expected in these models based on the following arguments Both direct and indirect electroweak and flavor precision constraints on fermionic partners are milder than the ones on spin one resonances Also the naturalness pressure coming from the top partners is stronger than that induced by the gauge partners This observation implies that the search strategy for vector resonances at the LHC needs to be modified In particular we point out the importance of heavy gluon decays or other vector resonances to top partner pairs that were overlooked in previous experimental searches at the LHC These searches focused on simplified benchmark models in which the only new particle beyond the Standard Model was the heavy gluon It turns out that when kinematically allowed such heavyheavy decays make the heavy gluon elusive and the bounds on its mass can be up to 2TeV milder than in the simpler models considered so far for the LHC14 We discuss the origin of this difference and prospects for dedicated searchesThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
