    Abstract: Following the discovery of a new boson with a mass around 125 GeV by the ATLAS and CMS collaborations at the LHC, significant progress has been made in understanding its properties with data taken up to 2012. The status of these measurements will be summarized and a statement of compatibly with the Higgs boson in the Standard Model will be made. A number of anomalies, however, are observed in the data. The data collected by ATLAS is indicative of a distortion of the Higgs boson transverse momentum spectrum. In addition, excesses are observed in the search for di-Higgs boson resonance with a mass around 300 GeV. A phenomenological framework is presented that is able to accommodate these anomalies. Whether these anomalies are due to a set of statistical upward fluctuations or new physics beyond the Standard Model will be resolved with data that will be delivered by the LHC in 2015 and 2016. Recent progress in Higher Order corrections to Higgs boson production at the LHC will also be summarized.
