The discovery of the Higgs boson at the LHC in 2012 has been a tremendous achievement, marking the end of a decade-long quest and completing the Standard Model of Particle Physics (SM). More than an end, the discovery marked the beginning of a new quest: pushing the boundaries of what we can measure and looking for even minute differences from SM expectations that could indicate new physics. In this project, following Galileo Galilei's “Measure what is measureable and make measureable what is not so”, we are using a combination of advanced machine learning and new calibration algorithms to sustain and even improve the performance of our existing detector. The effort focuses on the forward detector region, that is instrumental for the study of vector boson scattering (VBS), a process intimately linked to the nature of the Higgs boson. We will analyse VBS in the “all-jets” final state that has previously been considered to be too challenging to measure and was left uncovered up to now.
