Z' to tau tau - emu final state
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 s = 8 TeV recorded by the CMS experiment at the LHC. The data correspond to an integrated luminosity of 19.7 fb1. 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 (ZSSM masses excluded up to 1300 GeV) and for the GUT-inspired E6 model (Zψ 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 ΛT up to 2800 GeV.
