Project summary

The Standard Model (SM) of Particle Physics is an astoundingly precise description of a range of phenomena, yet experimental data shows us it can’t be the whole story. From the nature of dark matter, to the observed dominance of matter over antimatter, there are several open questions that drive the research into the most fundamental building blocks of Nature. Experimental or theoretical breakthroughs are needed for us to unravel the mysteries of the Universe.The vastness of the Large Hadron Collider (LHC) dataset, most of it yet to be delivered, is one of our best opportunities to shed light on some of the Universe’s mysteries. If the discovery of new physics is within reach of the LHC (including its high-luminosity phase, the HL-LHC), the Higgs boson may be our path to discovering it. Measuring the properties of the Higgs boson with the best possible precision is of the highest priority, as any deviation would take us beyond-the-SM.With this project I will boost Higgs bosons precision measurements at the LHC and future colliders, by exploring novel cutting-edge differentiable programming tools. A search for charge-parity violation in Higgs boson couplings to the W boson will be done for the first time, pioneering novel machine-learning-based inference techniques. In addition, the ability to perform precision measurements in future colliders will require detector designs beyond the current state-of-the-art.I will develop a proof-of-concept application of differentiable programming towards physics-oriented detector design, with a focus on hadronic calorimetry for a future Higgs boson factory.All together, this project expands the horizons of particle physics research. It lays the foundation for maximising the discovery potential of the LHC via innovative techniques that can achieve precision beyond the state-of-the art and directly impact what new physics can be found. It also sets the stage for the long-term future of the field by contributing towards a new paradigm of detector design that is driven by physics goals and can massively improve the achievable performance.
