K+K- photoproduction in ultra$-$peripheral Pb$--$Pb collisions

Nuclear Experiment 2024-05-07 v1 High Energy Physics - Experiment

Abstract

In ultra-peripheral collisions (UPCs) of relativistic heavy ions, photoproduction occurs when a photon emitted from one nucleus interacts with the other nucleus from the opposing beam, producing particles in the final state. Measurements of \KK photoproduction probe interactions and couplings between the ϕ(1020)\phi (1020) and charged kaons with photons and nuclear targets. We report exclusive \KK photoproduction cross section at midrapidity in \PbPb collisions at \snn = 5.02 TeV, which is measured for the first time in UPCs.
