"What is perhaps the most important piece of our theory of elementary particles and their interactions, aptly named the ""Standard Model"" (SM), has finally been discovered. The discovery of this particle, the Higgs boson, at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN), marked the culmination of years of hard work by thousands of experimental and theoretical Physicists. However, this discovery has left us with many unanswered questions, some of which the applicant's work aims to address. Specifically, the proposed project aims to improve the prospects for measuring the Higgs boson self-coupling, an important quantity in determining the role of the particle in the mechanism of the generation of masses in the SM. The proposed project will accomplish this by developing advanced Monte Carlo event generator tools for the production of pairs of Higgs bosons at the LHC, as well as improving the search strategies for channels via modern jet sub-structure and statistical techniques. Additionally, the effects of potential New Physics that could appear in the process will be examined and quantified in detail. The applicant's knowledge and experience as an author of the Herwig++ general-purpose Monte Carlo event generator, an important tool used by experimentalists, are crucial towards achieving his objectives. The Host Organization, CERN, provides the ideal location for the application to strengthen his ties with the experimental physicists working there, as well as maintain his excellent global collaborative connections."
