Higgs & new physics searches with ATLAS

This talk covers the results of a search for the Standard Model Higgs boson in proton-proton collisions with the ATLAS detector at the LHC. The datasets used correspond to integrated luminosities of approximately 5.0 ifb collected at $sqrt{s}$=7 TeV in 2011 and 5.5 ifb at $sqrt{s}$= 8 TeV in 2012. Individual searches in the channels Hql, Hgg and HWW in the 8 TeV data are combined with previously published results of searches for Hql, Hgg, HWW, Hbb and Htau in the 7 TeV data and results from improved analyses of the channels Hql, Hgg in the 7 TeV data. Clear evidence for the production of a neutral boson with a measured mass of 126.0 ± 0.4 (stat) ± 0.4 (sys) GeV is presented. This observation, which has a significance of 5.9 standard deviations is compatible with the production and decay of the Standard Model Higgs boson. Searches for signs of physic beyond the standard model, in a large variety of signatures are also presented with any experimental evidence.
