Abstract：
The φ-charmonium dissociation reactions in hadronic matter are studied. Unpolarised cross sections for φJ/ψ→D_s^- D_s⁺, φJ/ψ→D_s^*- D_s⁺ or D_s^- D_s^*+, φJ/ψ→D_s^*- D_s^*+, φψ'→D_s^- D_s⁺, φψ'→D_s^*- D_s⁺ or D_s^- D_s^*+, φψ'→D_s^*- D_s^*+, φχ_c→D_s^- D_s⁺, φχ_c→D_s^*- D_s⁺ or D_s^- D_s^*+ and φχ_c→D_s^*- D_s^*+ are calculated in the Born approximation, in the quark-interchange mechanism and with a temperature-dependent quark potential. The potential leads to remarkable temperature dependence of the cross sections. With the cross sections and the φ distribution function we calculate the dissociation rates of the charmonia in interactions with the φ meson in hadronic matter. The dependence of the rates on temperature and charmonium momentum is relevant to the influence of φ mesons on charmonium suppression.
