The extraction of $ϕ-N$ total cross section from $d(γ,pK^{+}K^{-})n$

Abstract

We report on the first measurement of the differential cross section of $ϕ$-meson photoproduction for the $d(γ,pK^{+}K^{-})n$ 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 $d(γ,pK^{+}K^{-})n$ channel and those from a previous publication on coherent $ϕ$ production on the deuteron has been carried out to extract the $ϕ-N$ total cross section, $σ_{ϕN}$. The extracted $ϕ-N$ total cross section favors a value above 20 mb. This value is larger than the value extracted using vector-meson dominance models for $ϕ$ photoproduction on the proton.
