Figure 8

Prediction of the dipole model for the $t$ distribution of coherent $J/\psi$ photoproduction on nuclei assuming that the single-nucleon distribution can be identified with the Woods-Saxon distribution given in the Appendix. Statistical errors of the simulated measurements are based on the assumed collected sample of ${10}^6$ events. The dashed line near the top shows the sum of the coherent and incoherent process in the case of no correlations.Reuse & Permissions

Figure 11

The $y$ range with good acceptance for reconstructing $J/\psi$ decays in the central region is plotted as a function of the electron beam energy [shaded (red) area] at $E_p=100$ GeV. The two curves indicate the minimum $y$ values for detecting the beam electron scattered at $0^{°}$ assuming (upper curve) that a 1-Tm dipole is placed near the interaction point (IP) and that the scattered electron should be at least $5$ cm from the beam $5$ m downstream of the dipole and assuming (lower curve) that a 5-Tm dipole is placed near the IP and that the scattered electron should be at least $5$ cm from the beam $10$ m downstream of the dipole.Reuse & Permissions
