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.8 p.application/pdfeng(c) American Physical Society, 2012Física nuclearCol·lisions (Física nuclear)Partícules (Física nuclear)HadronsNuclear physicsCollisions (Nuclear physics)Particles (Nuclear physics)Hadronsinfo:eu-repo/semantics/article6128252014-02-26info:eu-repo/semantics/openAccess
