| Abstract: A search for new physics beyond the standard model in the high-mass ditau final state with one tau decaying in the electron channel and one tau decaying in the muon channel is performed using proton-proton collisions at $\sqrt{s}$ = 8 TeV recorded by the CMS experiment at the LHC. The data correspond to an integrated luminosity of 19.7 fb$^{-1}$. The data are in good agreement with the standard model prediction. An upper limit at 95$\%$ CL on the product of cross section times branching fraction into tau pairs is calculated as a function of the resonance mass for the Sequential Standard Model $Z'$ ($Z'_{SSM}$ masses excluded up to 1300 GeV) and for the GUT-inspired $E_6$ model ($Z'_{\psi}$ masses excluded up to 810 GeV). The results are further interpreted in terms of the Arkani-Hamed, Dimopolous, and Dvali (ADD) model, setting an exclusion limit on the parameter $\Lambda_T$ up to 2800 GeV. | ||
