 Search for pair production of gluinos decaying via stop and sbottom in events with $b$-jets and large missing transverse momentum in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector / ATLAS Collaboration A search for Supersymmetry involving the pair production of gluinos decaying via third-generation squarks to the lightest neutralino is reported.

 Search for low mass Higgs-boson like resonances at CMS / Courbon, Benoit (Lyon, IPN) /CMS Collaboration A search is performed on the 8 TeV LHC data for additional scalars and pseudoscalar with masses below the newly discovered higgs boson h(125). These searches are motivated within several BSM theories, most significantly extensions of the non mininal extensions of the MSSM like the NMSSM, where additional scalar and pseudoscalar states are expected.

 Searches for supersymmetry in events with one or more leptons using the ATLAS and CMS experiments / Kirschenmann, Henning (CERN) /ATLAS and CMS Collaborations Recent results from searches for supersymmetry in final states with one or more leptons by the ATLAS and CMS collaborations are reported. The data for these results has been recorded in 2015 at $\sqrt{s}=13$\,TeV and amounts to an integrated luminosity of 2.2 - 2.3 fb$^{-1}$ for the CMS experiment and 3.2 fb$^{-1}$ for the ATLAS experiment.

 Dark Matter search at LHC / Pazzini, Jacopo (INFN, Padua ; Padua U.) /ATLAS and CMS Collaborations The results of recent searches for dark matter at the Large Hadron Collider at CERN are reported.The searches for dark matter performed with the first data collected during the LHC Run-2 by the CMS and ATLAS collaborations, corresponding to 2.1~\fb and 3.2~\fb of proton-proton collisions at $\sqrt{s}=13~\TeV$ respectively, are presented and categorized according to the event topology characteristics.No excesses are found above the standard model expectations and the results are interpreted in terms of upper limits in the production of dark matter using simplified theory models.The results are also translated into limits on the dark matter-nucleon spin-dependent and spin-independent cross section to compare with the results of direct detection experiments..

 Search for W' production in the lepton+MET final state at 13 TeV in CMS / Escalante Del Valle, Alberto (Madrid, CIEMAT) /CMS Collaboration This note presents the search for new physics in events with an electron or muon and missing transverse energy, using 2.2 $\rm{fb^{-1}}$ of pp collision data at a centre-of-mass energy of 13 $\rm{TeV}$, collected with the CMS detector during 2015. The focus is set on the potential production of a W' boson, as described by the Sequential Standard Model. [...] CMS-CR-2016-094.- Geneva : CERN, 2016 - 7 p.

 Search for New Physics in Z+MET channel at CMS / Brodski, Michael (Aachen, Tech. Hochsch.) /CMS Collaboration Despite the great understanding of particle interactions in terms of the Standard Model and the recent discovery of the Higgs boson at the LHC, the Standard Model of particle physics can not yet explain various phenomena, such as neutrino masses or the Dark Matter halo in the galaxies. This talk presents new LHC Run II results of a search for New Physics in Z+MET channel, discussing the main experimental features along the uncertainties and finally giving an outlook for the future data in Run II..

 The diphoton as the Higgs of the Higgs / Kannike, Kristjan ; Pelaggi, Giulio Maria ; Salvio, Alberto ; Strumia, Alessandro LHC results do not confirm conventional natural solutions to the Higgs mass hierarchy problem, motivating alternative interpretations where a hierarchically small weak scale is generated from a dimension-less quantum dynamics.

 Search for top squark pair production in compressed-mass-spectrum scenarios in proton-proton collisions at $\sqrt{s} =$ 8 TeV using the ${\alpha_\mathrm{T}}$ variable / CMS Collaboration An inclusive search is performed for supersymmetry in final states containing jets and an apparent imbalance in transverse momentum, $\vec{p}_{\mathrm{T}}^{\text{miss}}$, due to the production of unobserved weakly interacting particles in pp collisions at a centre-of-mass energy of 8 TeV.
