The Large Hadron Collider (LHC) at CERN has allowed the ATLAS and CMS experiments to collect a large amount of proton‐proton collision data at 7 TeV and 8 TeV centre‐of‐mass energies. This dataset was used to discover a Higgs boson with Standard Model‐like properties at a mass of about 125 GeV. In parallel, an impressive number of searches for deviations from the Standard Model expectations have been carried out in various physics areas (BSM Higgs, Supersymmetry, and Exotics). Representative searches in all of these domains will be presented and their impact on theoretical models beyond the SM assessed. To date, there is no evidence in the LHC data of a signal for New Physics beyond the SM. However, a few legacy 2–3δ deviations remain from both experiments. After an 18‐month shutdown, the LHC is about to deliver collision data at an increased centre‐of‐mass energy of 13 TeV. The large increase in collision energy will provide much improved sensitivity for various searches, in particular for high mass particles. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
