Title: Broad composite resonances and their signals at the LHC

Journal Article · · Physical Review. D.
; ; ORCiD logo

The existence of the SU(2)(L) triplet composite spin-1 resonances rho(+/-,0) is a universal prediction of the strongly interacting new physics addressing the naturalness problem. Such resonances have not been found in the diboson final states, which are expected to be the dominant decay channels. In this work we propose a new scenario where the left-handed quark doublet q(L) = (t(L), b(L)) is fully composite. In this case, the rho resonances can be broad and mainly decay to the third-generation quarks. The t (t) over bar resonance search channel is comparable in sensitivity to the dilepton channel. In addition, the same-sign dilepton channel in t (t) over bar rho(0)-associated production can probe the large-width region and complement the Drell-Yan production channels.
