The Standard Model is the predominant and most fundamental theory in particle physics for our understanding of the universe at the deepest level. It explains the origin of mass and matter in terms of a specific collection of fundamental particles and their forces. Using the Large Hadron Collider (LHC) of CERN, experiments of large international collaborations test the Standard Model and discover its basic properties from high energy collisions of particles by studying the pieces that result from the collisions. This is how the Higgs particle was recently discovered earning the Nobel prize for its inventors. The LHC will soon undergo a 14 TeV energy upgrade and the new energies available to the LHC14 will extend the search for fundamental new physics Beyond the Standard Model (BSM). The recently discovered Higgs boson could play the role of an important messenger of new BSM physics. Predicted by the Standard Model, the Higgs boson is described as a fundamental particle responsible for the origin of mass in the universe. However, at a deeper level, the Higgs could be a composite of new fundamental particles waiting for discovery in the BSM paradigm. The measured properties of the Higgs as detected by the LHC are not precise enough to validate the Standard Model to the exclusion of alternative composite Higgs models. Based on this team’s recent exploratory studies, a promising candidate theory is identified for an alternative composite Higgs mechanism which may be revealed by the LHC14 upgrade. This project supports further investigations in an effort to confirm the preliminary findings with exciting potential for discovery. The outcome of the project will come from the detailed analysis of the theory from simulations that are important for the experimental search of the composite Higgs scenario at the LHC14 looking for evidence of new physics Beyond the Standard Model.
