TeV, again at 5(3) σ and for electrons and muons, respectively, for a suitable choice of the coupling. 

As we can see in figure 6, 75(110) pb − 1 of data is the minimum integrated luminosity required to access the coupling g ′ 1 = 0 . 1 at 3 σ , in the electron(muon) final state, while 200(320) pb − 1 is required to access the same coupling at 5 σ , for a Z ′ B − L boson mass of ∼ 800 GeV, where Z ′ B − L → e $^{+}$e $^{−}$( µ $^{+}$µ $^{−}$). For a coupling of 0 . 2, 150(500) pb − 1 and 210(550) pb − 1 are the minimum luminosities to start having evidences, at 3(5) σ , of the Z ′ B − L boson decaying into electrons and muons, respectively. 

If a √$_{s}$ = 10 TeV run at the LHC is performed and is able to collect up to 1 fb − 1 of data, it would be possible to discover(observe) a Z ′ B − L for masses up to 1 . 2(1 . 45) TeV and 1 . 10(1 . 35) TeV (at 5(3) σ ) by looking at electrons and muons in the final state, respectively, for g ′ 1 = 0 . 1, and 1 . 60(1 . 95) TeV and 1 . 55(1 . 85) for g ′ 1 = 0 . 2. 

The 5 σ discovery potential for the LHC at √$_{s}$ = 10 TeV is summarised in table IV, for selected values of couplings and integrated luminosities. 

For illustrative purposes, we choose several benchmark points on the 3 σ and 5 σ lines for
