The light unflavoured meson η/η decays are valuable for testing non-perturbative quantum chromodynamics and exploring new physics beyond the Standard Model. This paper describes a series of event generators, including η/η → γl, which have been developed for investigating η/η decay dynamics. For most of these generators, their usability has been validated in BESIII analyses for determining the detection efficiency, and background studies. The consistency between data and Monte Carlo shows that these generators work well in the BESIII simulation, and will also be useful for ongoing BESIII analyses and other experiments for studying η/η physics.

“…Therefore, the systematic error on the background subtraction was determined by performing several different fits of the background and taking the standard deviation. The error on the acceptance due to the uncertainties on the transition form factor is found to be negligible by varying the vector dominance model value of the b η by ±10% to accommodate the most recent experimental results [17,18,23,24].…”

Radiative corrections to the η(′) Dalitz decays

et al. 2018

We provide the complete set of radiative corrections to the Dalitz decays η ð0Þ → l þ l − γ beyond the softphoton approximation, i.e., over the whole range of the Dalitz plot and with no restrictions on the energy of a radiative photon. The corrections inevitably depend on the η ð0Þ → γ Ã γ ðÃÞ transition form factors. For the singly virtual transition form factor appearing, e.g., in the bremsstrahlung correction, recent dispersive calculations are used. For the one-photon-irreducible contribution at the one-loop level (for the doubly virtual form factor), we use a vector-meson-dominance-inspired model while taking into account the η-η 0 mixing.
