Non Minimal Higgs

"This project focuses on new physics models with a non-minimal Higgs sector. On 4h July 2012 CERN announced the discovery of a scalar particle at the Large Hadron Collider (LHC), a Higgs boson. This long awaited discovery increased massively our understanding of Nature. To illustrate the phenomenal importance of this discovery, it suffices to mention that it resulted in the 2013 Nobel Prize in Physics to Profs PW Higgs and F Englert ``for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN's Large Hadron Collider“ (motivation of the Nobel Committee). In connection with this, we should also like to report a few quotes. Peter Knight, president of UK's IoP: ""This is the physics version of the discovery of DNA“. Former British PM David Cameron: ""This is a great breakthrough, one that could be profoundly significant to our understanding of the universe and the fundamental laws that govern it“. German Research Minister Annette Schavan: ""The endurance and curiosity of researchers has been rewarded"". This is all very exciting. However, there are still fundamental questions awaiting an answer. Since the Standard Model (SM), the theoretical framework which predicted the experimental discovery of the Higgs boson, appears flawed, which new physics scenario better describes Nature when all observed properties of this new particle are taken into consideration? Will any of these new models help to solve other outstanding problems in particle physics? The overall objective of this project is to look for answers to these crucial questions. The path that we are taking to do so is guided by the following considerations. The SM is incomplete, in fact, it cannot explain other physics phenomena observed in the Universe (why there is dark matter, why there are more particles than antiparticles, why neutrinos are massive, etc.). There is therefore a need to go Beyond the SM (BSM). However, the Higgs mechanism for the generation of mass must be a cornerstone of any BSM scenario. We are therefore exploring a variety of scenarios that embed the Higgs mechanism in a (non-minimal) form suitable for BSM physics and we are studying their manifestations in both laboratory and space facilities, as these will provide the unlocking key to what BSM physics is realised in Nature."
