Figure 7: Pseudo-rapidity distributions of electrons for signal and background at √ s $^{= 1}$.4 TeV and Λ = 10 TeV. Figure 8: ej invariant mass distributions for signal and background at √ s $^{= 1}$.4 TeV and Λ = 10 TeV. Advantage of resonant production will provide an opportunity to probe compositeness scale will above the center of mass energy of the collider. For statistical significance we use following formula: where S and B denote number of signal and background events, respectively. Numbers of signal and background events for different M$_{e}$ 8 values are presented in Table 2 for L$_{int}$ = 1 fb − $^{1}$. In calculating these values, in addition to cuts given above, we have 7 SS = S √$_{S}$$_{+}$$_{B}$ (3) 10 -4 10 -3 10 -2 10 -1 10 0 10 1 10 2 -4 -3 -2 -1  0  1  2  3  4 (1/$^{σ}$ ) d$^{σ}$ /d Background(e $^{-}$) M$_{e8}$ =500 GeV (e$^{-}$ ) M$_{e8}$ =750 GeV (e$^{-}$ ) M$_{e8}$ =1000 GeV(e $^{-}$ ) 10 -6 10 -4 10 -2 10 0 10 2  400  600  800  1000  1200  1400 d /dM ej (pb/GeV) M$_{je}$ - (GeV) Background(j,e $^{-}$) m$_{e8}$ =500 GeV m$_{e8}$ =750 GeV m$_{e8}$ =1000 GeV
