Simulated invariant mass distribution of e⁺e⁻γ from one-month operation at the Huizhou η factory, assuming a conservative inelastic reaction rate of 100 MHz with 30% beam duty factor

Caption

The future Huizhou η factory will produce unprecedentedly large quantities of π⁰ and η mesons, pushing the intensity and precision frontiers in the hundreds-of-MeV energy domain. The abundant η meson samples will enable investigations into fundamental particle physics questions, including searches for hypothesized light portal particles and studies of symmetry-breaking effects in strong interactions.
