Title: The extraction of ΦN total cross section from d(γ,pK+K-)n

We report on the first measurement of the differential cross section of $$\phi$$-meson photoproduction for the $$d(\gamma,pK^{+}K^{-})n$$ exclusive reaction channel. The experiment was performed using a \textcolor{black}{tagged-photon} beam and the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. A combined analysis using data from the $$d(\gamma,pK^{+}K^{-})n$$ channel and those from a previous publication on coherent $$\phi$$ production on the deuteron has been carried out to extract the $$\phi-N$$ total cross section, $$\sigma_{\phi N}$$. The extracted $$\phi-N$$ total cross section favors a value above 20 mb. This value is larger than the value extracted using vector-meson dominance models for $$\phi$$ photoproduction on the proton.
