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 3.24TeV. Excited chiral bosons (W∗) with equivalent coupling strengths are excluded for masses up to 3.21TeV. In the framework of an effective field theory limits are also set on the dark matternucleon 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 UR - http://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000526594 ER -
