K+K- photoproduction in ultra$-$peripheral Pb$--$Pb collisions / Kim, Minjung (UC, Berkeley ; SUNY, Stony Brook)
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. [...]

Girth and groomed radius of jets recoiling against isolated photons in lead-lead and proton-proton collisions at $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = $ 5.02 TeV / CMS Collaboration
This Letter presents the first measurements of the groomed jet radius $ R_{\mathrm{g}} $ and the jet girth $ g $ in events with an isolated photon recoiling against a jet in lead-lead (PbPb) and proton-proton (pp) collisions at the LHC at a nucleon-nucleon center-of-mass energy of 5.02 TeV. [...]
