No significant excess beyond Standard Model expectations is observed. A W' with Sequential Standard Model couplings is excluded at the 95% confidence level for masses up to 3.24 TeV. Excited chiral bosons (W*) with equivalent coupling strengths are excluded for masses up to 3.21 TeV. In the framework of an effective field theory limits are also set on the dark matter-nucleon scattering cross-section as well as the mass scale M-* of the unknown mediating interaction for dark matter pair production in association with a leptonically decaying W. %K Hadron-Hadron Scattering %K Beyond Standard Model %R 10.1007/JHEP09(2014)037 %U http://arxiv.org/abs/arXiv:1407.7494 %U https://doi.org/10.1007/JHEP09(2014)037 %P 037-43pp
