“…The SPring-8 [15] and JLab [16] results are consistent with the JLab measurements of coherent [7] and incoherent [22] φ photoproduction from deuterium. The coherent data suggest that σ φN ≈ 30 mb together with a larger slope for elastic φN scattering compared to γ N → φN [7].…”

“…Whereas medium modifications of σ φN might offer a plausible explanation of the SPring-8 [15] and JLab [16] data, they can hardly account for the large value found in deuterium. Nuclear density effects are here minimal and other mechanisms, beyond medium modifications, could be more important [22].…”

“…Values of the in-medium σ φN were also determined by the CLAS Collaboration from transparency ratio measurements at JLab [16]. In this experiment, the φ mesons were photoproduced on 2 H, C, Ti, Fe, and Pb targets and detected via their e + e − decay mode.…”

The production of φ mesons in proton collisions with C, Cu, Ag, and Au targets has been studied via the φ → K + K − decay at an incident beam energy of 2.83 GeV using the ANKE detector system at COSY. For the first time, the momentum dependence of the nuclear transparency ratio, the in-medium φ width, and the differential cross section for φ-meson production at forward angles have been determined for these targets over the momentum range of 0.6-1.6 GeV/c. There are indications of a significant momentum dependence in the value of the extracted φ width, which corresponds to an effective φN absorption cross section in the range of 14-21 mb.

Information on the properties of the φ meson in the nuclear environment has been derived from its production in proton collisions with C, Cu, Al, and Au nuclear targets. The experiment was carried out with 2.83 GeV protons at the Cooler Synchrotron COSY, with the φ being detected via its K + K − decay using M. Hartmann et al. the ANKE magnetic spectrometer. The measured dependence of the production cross section on the nuclear mass number has been compared with calculations within three different nuclear models. These suggest a significant broadening of the width of the φ in medium relative to its vacuum value. The ANKE results obtained in the momentum range 0.6 < p φ < 1.6 GeV/c are compared with data from photoproduction experiments at slightly higher momenta.
