Production of strangeonium $$\phi (1680)$$ state in electromagnetic probe-driven scatterings and hadron–hadron ultraperipheral collisions

Abstract

AbstractIn this work, the$$\gamma p\rightarrow \phi (1680) p$$γp→ϕ(1680)preaction is systematically studied based on the two gluon exchange model and the pomeron model. The calculation results show that the total cross section of$$\phi (1680)$$ϕ(1680)photoproduction can reach more than 80 nb near the center-of-mass energy$$W=4$$W=4 GeV, so it is suggested that JLab and other experiments carry out relevant measurements. Moreover, under the framework of the vector meson dominance assumption, the scattering length of$$\phi (1680)$$ϕ(1680)and proton interaction is estimated as$$0.07\pm 0.01$$0.07±0.01 fm from the cross sections predicted by the theoretical models, which is on the same order of magnitude as the$$\phi (1020)$$ϕ(1020)-pscattering length. In addition, the total cross section, number of events and rapidity distribution of$$\phi (1680)$$ϕ(1680)production are predicted at Electron-Ion colliders (EICs) and ultra-peripheral collisions (UPCs) by using eSTARlight and STARlight code. The study of$$\phi (1680)$$ϕ(1680)and relevant properties is of enlightening significance in better understanding the strangeonium family spectrum, and provides necessary data support for the future experiment of EICs and UPCs.
