 Measurement of $\tau$ polarisation in $Z/\gamma^{*}\rightarrow\tau\tau$ decays in proton--proton collisions at $\sqrt{s}=8$ TeV with the ATLAS detector This paper presents a measurement of the polarisation of $\tau$ leptons produced in $Z/\gamma^{*}\rightarrow\tau\tau$ decays which is performed with a dataset of proton-proton collisions at $\sqrt{s}=8$ TeV, corresponding to an integrated luminosity of 20.2 fb$^{-1}$ recorded with the ATLAS detector at the LHC in 2012.

 Searches for new physics in lepton+jet final states in ATLAS and CMS / Romeo, Francesco (Beijing, Inst. High Energy Phys.) /ATLAS and CMS Collaborations The most recent results on searches in lepton plus jet final states motivated bydifferent models beyond the standard model are presented, using pp collision datacollected by the ATLAS and CMS detectors during Run I and Run II at theCERN LHC. Leptoquarks and heavy Majorana neutrinos that arise in theleft-right model are looked for in the final states with two leptons and two jets( ll + jj, l = e, mu, tau ).

 ELECTROWEAK MEASUREMENTS AT THE LHC / Savin, Alexander (Wisconsin U., Madison) /ATLAS and CMS Collaborations A set of selected electroweak measurements from the LHC experiments is discussed. Results on forward-backward asymmetry in production of the Drell-Yan events in both dielectron and dimuon decay channels are presented together with results on the effective mixing angle measurements. Angular coefficients measured in the Z boson production are compared with theoretical predictions. [...] CMS-CR-2017-209.- Geneva : CERN, 2017 - 9 p.

 Single top t-channel / Faltermann, Nils (KIT, Karlsruhe, EKP) /ATLAS ,CMS and Top Collaborations The production of single top quarks allows to study the interplay of top quark physics and the electroweak sector of the standard model. Deviations from predictions can be a hint for physics beyond the standard model. [...] CMS-CR-2017-207.- Geneva : CERN, 2017 - 7 p.
