In the realm of energy and particle physics, a team of researchers from the European hadron physics community has developed a significant resource that could have implications for our understanding of fundamental particles and forces. The researchers, Lorenzo Cotrozzi, Anna Driutti, Fedor Ignatov, Alberto Lusiani, and Graziano Venanzoni, are part of the RadioMonteCarLow2 Working Group (RMCL2 WG), which aims to enhance the theoretical description of scattering processes at electron-positron colliders.
The team has created PrecisionSM, an annotated database that compiles data on low-energy cross sections of electron-positron collisions into hadronic channels. This data is crucial for the theoretical evaluation of the muon anomalous magnetic moment, a precise test of the Standard Model of particle physics. The database is accessible through a custom website, which provides detailed information about the data samples, including the treatment of radiative corrections, and links to relevant papers and tables.
The database currently contains data for the dominant 2π channel, as well as for the 3π and π0γ channels. The researchers are actively working to expand the database to include other channels and to develop responsive plots. This ongoing work is part of the RMCL2 WG’s broader goal of improving the theoretical description of scattering processes at electron-positron colliders.
The PrecisionSM database was initially developed within the STRONG2020 group application of the European hadron physics community. It has since been incorporated into the RMCL2 WG activities. The results of Phase I of the RMCL2 WG have been published in a paper available on arXiv, a popular preprint server for physics and related fields (arXiv:hep-ph/2410.22882).
While this research is primarily focused on fundamental particle physics, it has potential applications in the energy sector. A deeper understanding of the Standard Model and the behavior of particles at low energies can contribute to the development of new technologies and energy sources. For instance, advancements in particle physics have historically led to innovations in fields such as medical imaging, nuclear energy, and particle accelerators, which are used in various industrial and research applications. Therefore, the PrecisionSM database and the ongoing work of the RMCL2 WG could indirectly support the energy industry by advancing our knowledge of fundamental physics.
