| Abstract: A search for $ \mathrm{ T'\bar{T'} \rightarrow W'^{+}b W'^{-}\bar{b} } $ in the dilepton final state is presented using pp collision data recorded by the CMS detector corresponding to 19.7 fb$^{-1}$ of integrated luminosity. The analysis is based on a two-dimensional mass reconstruction of the $ \mathrm{ T' \bar{T'} } $ system performed without assumptions about the underlying theory except the event topology. No significant excess over the standard model predictions is observed. We set 95% confidence level upper limits on a simplified little Higgs model. | ||

| Summary |
| A search for $ \mathrm{ pp \to T' \bar{T}' \to W'^+ b W'^- \bar{b} } $ in the dilepton final state has been performed using 19.7 fb$^{-1}$ of data recorded by the CMS detector at $ \sqrt{s} =$ 8 TeV. The analysis is based on a two-dimensional mass reconstruction of the $ \mathrm{ T' \bar{T}' } $ system without assumptions about the underlying theory except the event topology. No deviation from standard model predictions is observed. The region excluded from the search region defined above is up to a $ M_{ \mathrm{T'} } $ range of 800-920 GeV, depending on $ M_{ \mathrm{W'} } $. This is the first dedicated search performed at the LHC for both a new heavy top partner and a new heavy charged gauge boson as predicted by the littlest Higgs model. |
