Project title: A Computable Composite 2-Higgs Doublet Model
Main applicant: Stefano Moretti, Division of High Energy Physics
Grant amount: SEK 794 100 over three years, project funding/scholarship to recruit a postdoc and operation of the research project in the summary
The Higgs boson discovered at the Large Hadron Collider could be the first manifestation of a mechanism of Electro-Weak Symmetry Breaking (EWSB) richer than the minimal one of the Standard Model (SM). Indeed, the SM is non-minimal in both its matter and interactions so that it is well motivated to postulate a non-minimal Higgs sector too. Scenarios with a 2-Higgs Doublet Model (2HDM) structure represent an intriguing possibility. These are in fact necessary to Supersymmetry and natural to Compositeness, the two paradigms that most satisfactorily address the SM hierarchy problem. Our goal is to promote Compositeness in its 2HDM realisation (C2HDM) to being a computable alternative to the Minimal Supersymmetric SM (MSSM), in terms of both theoretical predictions and experimental tests, through a phenomenological study ranging from model building to data analysis. To accomplish this, we will develop dedicated tools enabling Monte Carlo (MC) simulations ensuring that Compositeness will not remain the current abstract conception that it is but rather will be tested against reality. The inter-disciplinary aspects of the proposed research programme will be fostered by host, the High Energy Physics division at Uppsala University, comprising both theorists and experimentalists.
