Understanding the Early Universe: interplay of theory and collider experiments
University of Warsaw ·Poland
About this project
<p> This project is focused on full exploration of the opportunities that will be provided by the collider experiments in the forseeable future, with the upgrades of the LHC. Its goal is to attack the questions relevant for the very early history of the universe. It will result in improved methods of the data analysis and of their presentation, based on the guiding by a broad spectrum of the existing and new theoretical models, analyzed from a new angle of documenting the similarities and differences in their experimental signatures. On several instances new data analysis techniques and new theoretical constructions will be investigated. Furthermore, theoretical interpretation of the potential new discoveries will be studied. This programme requires close collaboration between experimentalists and theorists. Our tasks, motivated by the goal of understanding the early universe are: 1) Machine learning assisted monojet analysis in search for dark matter and new electrically neutral stable particles and theoretical interpretation of the future data. 2) Discriminating theories by joint monojets and mono-higgs boson analyses. 3) Constraining the mechanism of the Electroweak Phase Transition by di-higgs boson production. 4) Probing new sources of CP violation in the Higgs-fermion sector. 5) Investigating the sphaleron and mini-black hole production at the LHC and its dependence on the mechanism of the EW phase transition. The proposed collaboration is meant not to interfere with the Bergen group participation in the ATLAS collaboration. Realistic but not proprietary simulations of experimental capabilities will be used. We see our collaboration as focused on searching for not yet fully explored signatures and the methods of analyses, as well as new ways of presenting their results, inspired by the Warsaw theorists proposals. </p>
Bilateral cooperation results
Bilateral collaboration was satisfactory and documented by publications. Four papers have common co-authors from Warsaw and Bergen. This number is also the same that the target value of common papers. Moreover, a joint ERC grant was submitted.
