extracted from these data are quite looser compared to those we will derive in the next section, therefore we will not show them. 

## IV. Z ′ BOSON SECTOR: DISCOVERY POWER 

In this section we determine the discovery potential of the LHC considering several center- of-mass (CM) energies, 7, 10 and 14 TeV, using the expected integrated luminosities. In the following subsection we present the latest available experimental constraints and we compare our results for the LHC to the expected ultimate reach at the Tevatron, for ∼ 10 fb − 1 [35]. ′ ′ 

The production cross sections for the process pp ( p ) → Z B − L for g 1 = 0 . 1 are shown in figure 2. Note that although at the Tevatron the production cross section is smaller than at the LHC, the integrated luminosities we are considering here for the LHC at 7 and 10 TeV (i.e., 1 fb − $^{1}$) are smaller than for the Tevatron (i.e., 10 fb − $^{1}$).
