Project objective

Extracting the polarisation of electroweak (EW) bosons from Large-Hadron-Collider (LHC) data represents a crucial step towards a deep understanding of the electroweak-symmetry-breaking (EWSB) mechanism realised in nature. Therefore, an accurate and realistic theoretical modelling is needed for polarised-boson production and decay in relevant LHC processes. In order to improve the current theoretical accuracy for polarised-bosons processes and to enable direct comparisons with experimental data, this research aims at the inclusion of higher-order corrections in the strong and EW couplings through a matching of fixed-order predictions to parton-shower programs. This will be carried out within the Standard Model (SM) of particle physics, as well as in the presence of beyond-the-SM effects, allowing for broad phenomenological investigations of the EWSB and fostering the development of polarisation taggers (also using modern machine-learning techniques) that will be beneficial for upcoming LHC analyses.
