Objective
The Standard Model of particle physics is our most comprehensive framework for describing the subatomic world. Among its fundamental parameters, the strong coupling constant is the least precisely known gauge coupling, with an uncertainty of about 0.8%.
The limited knowledge of the strong coupling poses a major obstacle to the current and future precision program of collider physics, particularly in view of the upcoming high-luminosity upgrade of the Large Hadron Collider (LHC) at CERN. Since the strong coupling enters every experimental measurement and theoretical prediction at the LHC, our unsatisfactory knowledge represents a bottleneck in the quest for precision.
One of the most established environments for the extraction of the strong coupling is given by event shapes in electron-positron collisions. However, event shapes are affected by significant non-perturbative corrections associated with hadronisation, for which no solid theoretical understanding is available. Hadronisation represents the most debated topic in strong coupling determinations from event shapes, with some research groups observing a tension of about three standard deviations from the current world average.
In this project, I will deliver the most advanced fit of the strong coupling constant to date from event-shape data within the gluer model, a framework for the description of hadronisation where recent results have opened the path towards a deeper understanding of its analytic structure. I will also explore the connections between predictions in the gluer model and hadronisation models implemented in Monte Carlo event generators, the most widely used tools to simulate and analyse particle collisions.
The outcomes of this project are crucial not only to fully exploit the potential of the LHC and its high-luminosity phase, but also for possible future facilities like the FCC-ee, where the ambitious per-mille accuracy target will set a new standard for theoretical predictions.
