Web26 de set. de 2024 · But a hidden sector of particles could help solve the hierarchy problem, said Zackaria Chacko, a physicist at the University of Maryland who was one of the first to propose this idea in the early 2000s. “Naively, the way you can think about it is, the Standard Model particles want to pull their Higgs up and make the Higgs heavy,” he said. WebProspects for long-lived particle searches at Belle II (Torben Ferber) 2 Super B-factory accelerator: SuperKEKB • Asymmetric beam energies: e.g. 7.0 GeV (e-) / 4.0 GeV (e+) • Large crossing angle of 83 mrad • Major upgrade to the accelerator with 30× the KEKB design luminosity (6×1035 cm-2s-1, 50 ab-1 (50× Belle)) • 1.5× higher beam currents, …
