The M2 internship can be expanded into a PhD project focused on the measurement and interpretation of the HH → bbγγ signal exploiting the full LHC Run 2 and Run 3 datasets.
The project will explore the separate treatment of various HH production modes to improve the analysis sensitiv- ity, and the final measurement will be designed to be robust against any deviation from the SM predictions, and to maximize sensitivity when interpreted in the context of Effective Field Theories (EFTs), such as the HEFT model. The analysis work will take place in the broader context of the ATLAS search for di-Higgs production in various decay channels, and a participation to Run 2 and Run 3 di-Higgs combination is foreseen. In parallel, the student will contribute to the improvement of the photon performance in ATLAS, with a strong connection to the understanding of the performance of the ATLAS Liquid Argon electromagnetic calorimeter with Run 3 data.
The duration of the PhD thesis is three years. The geographical proximity of LAPP and CERN, about 50 km and 35’ drive, will allow a strong involvement both with the data taking and detector operation and with the partici- pation in person to the working meetings of the ATLAS (di)Higgs Group. A period of several months of continuous presence at CERN is foreseen.
