LHC $Z^{\mathrm{‘}}$ discovery potential for models with continuously distributed mass

We study the Large Hadron Collider (LHC) discovery potential for $Z^{\mathrm{‘}}$ models with continuously distributed mass for $\sqrt{s}=7,10$ and 14 TeV centre-of-mass energies. One of possible LHC signatures for such models is the existence of broad resonance in Drell-Yan reaction $pp \to Z^` + … \to l^+l^-
