Absorption of $\psi (2S)$ mesons in nuclei

Abstract

In the present work we explore the inclusive $\psi (2S)$ meson photoproduction from nuclei near the kinematic threshold within the collision model, based on the nuclear spectral function, for incoherent direct photon--nucleon charmonium creation processes. The model takes into account the final $\psi (2S)$ absorption, target nucleon binding and Fermi motion. We calculate the absolute and relative excitation functions for production of $\psi (2S)$ mesons on ${}^{12}$C and ${}^{184}$W target nuclei at near-threshold photon beam energies of 8.0--16.4 GeV, the absolute momentum differential cross sections for their production off these target nuclei at laboratory polar angles of 0${}^{\circ }$--10${}^{\circ }$, the momentum dependence of the ratio of these cross sections as well as the A-dependences of the ratios (transparency ratios) of the total cross cross sections for $\psi (2S)$ production at photon energy of 13 GeV within the different scenarios for the $\psi (2S)N$ absorption cross section. We also calculate the A-dependence of the ratio of $\psi (2S)$ and $J/\psi$ photoproduction transparency ratios at photon energies around of 11.5 GeV within the adopted scenarios for this cross section. We demonstrate that both the absolute and relative observables considered reveal a definite sensitivity to these scenarios. Therefore, the measurement of such observables in future experiments at the upgraded up to 22 GeV CEBAF facility in the near-threshold energy region might shed light both on the $\psi (2S)N$ absorption cross section and on its part associated with the nondiagonal process $\psi (2S)+N\to J/\psi +N$ at finite momenta, which are of crucial importance in understanding of charmonium production and suppression in high-energy nucleus--nucleus collisions in a search for the quark-gluon plasma.
