الوصف: | As a Goldstone boson with zero quantum number and zero SM charge, the decays of long-lived $\eta$ ($\eta^{\prime}$) meson provide a unique window to search new physics beyond the standard model and new sources of CP violation, to test the low-energy QCD theory, and to measure the fundamental parameters of light quarks. For such goals in the physics frontiers we discuss a plan of building a super $\eta$ factory at HIAF high-energy terminal or at CiADS after upgrade. The high-intensity proton beam at HIAF provides a great opportunity of producing a huge number of $\eta$ samples of more than $10^{13}$ events per year, with multiple layers of thin targets of light nucleus. The physics goals, the first-version conceptual design of the spectrometer, and the preliminary simulation results are present. Comment: 19 pages, 9 figures |
