We present studies of the e + e − → K + K − γ reaction for the e + e − center-ofmass energies close to the φ(1020) meson mass. Different mechanisms leading to the final state are considered. The strong interaction amplitudes of the K + K − pairs in the Swave are taken into account. In addition, the photon emission in the initial state, the final state radiation effects and all the possible interference terms are included in the transition matrix elements. The K + K − effective mass distributions and the angular dependence of the reaction cross-section are calculated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
