In this paper, a data-driven method to precisely simulate the detector response of the anti-neutron depositing in the Electromagnetic Calorimeter (EMC) at BESIII is introduced. A large anti-neutron data sample can be selected using the decay J/ψ → pnπ − from the BESIII data sample of 10 billion J/ψ events. The detection efficiency for and various observables of anti-neutrons interacting in the EMC detector are simulated, taking the correlations among the variables into consideration. The systematic uncertainty of this data-driven simulation method is determined to be less than 1% on average. This method can be widely applied in physics processes that require precise simulation of the detector response of anti-neutrons in the EMC.

“…As the proton mass radius has already been fixed by the data of ω, φ, and J/ψ vector meson photoproductions near threshold in the previous analysis [15,17,18], we would like to see whether the neutron mass radius can be extracted in experiment as well. The recent time-like measurement of neutron shows that the effective form factor of neutron has the different oscillation behavior compared to that of proton [19]. It is interesting to see whether or not the mass distribution and mass radius of the neutron are different from those of the proton.…”

Tremendous progresses have been achieved for the proton structure and radius measurements, but not so many for the neutron. In this paper, we extract the mass radii of the neutron and the proton from the analysis of the differential cross sections of near-threshold ω and φ photoproductions on deuterium target, which is regarded as a quasi-free neutron plus a quasi-free proton. The incoherent data of ω and φ photoproductions are provided by CBELSA/TAPS collaboration and LEPS collaboration respectively, where the deuteron is disintegrated in the experiments to measure the properties of the individual nucleons. With the near-threshold data of γd → ωn(p) and γd → ωp(n), the neutron and proton mass radii are determined to be 0.795 ± 0.092 fm and 0.741 ± 0.028 fm respectively. With the near-threshold and incoherent φ photoproduction data of γd → φpn, the average mass radius of the bound nucleon (neutron or proton) inside the deuteron is extracted to be 0.752 ± 0.039 fm. For a comparison study, we also extract the mass radius of the free proton from the exclusive and inclusive ω photoproductions on the hydrogen target by the CBELSA/TAPS collaboration. From our analysis, we find that the neutron mass radius is close to the proton mass radius with no obvious difference, and the nuclear modification on the mass radius is not significant inside the deuteron.
