On July 4, 2012 CERN announced the discovery of a new boson at the Large Hadron Collider. Both the ATLAS and CMS collaborations independently observe the new boson with a mass at around 125 GeV, with properties crudely approximating those predicted for the Higgs boson of the Standard Model of particle physics. It is crucial to measure the quantum numbers and interaction strengths of the new particle, and compare to the detailed predictions for the Higgs boson made by the Standard Model. This will have a direct impact on searches for new phenomena at the LHC and beyond, and provide essential insights into the nature of possible new physics. In particular, searches for new particles can shed light on whether "naturalness" is relevant as a guiding principle for physics at the TeV scale.

This rapid response workshop aims at bringing together theorists, with expertise in collider phenomenology, Standard Model processes, and theories and models of TeV-scale physics beyond the Standard Model, and experimentalists working on the LHC Higgs analyses, to examine the status of the Higgs data as of December, 2012 and to assess its implications for future experimental and theoretical studies. New physics models that could explain any observed deviations from the Standard Model predictions or be ruled out by the current data set will be explored in detail, and suggestions will be developed for further improvements to the LHC Higgs data analyses. In addition, the workshop will evaluate the benefits of various strategies for precision Higgs experimental studies at future facilities such as higher energy and/or luminosity runs at the LHC and a Higgs factory at a future lepton collider.
