abstract
Moving highly-charged ions carry strong electromagnetic fields that act as a field of photons. In collisions at large impact parameters, hadronic interactions are not possible, and the ions interact through photon-ion and photon-photon collisions known as {\it ultra-peripheral collisions} (UPC). Hadron colliders like the Relativistic Heavy Ion Collider (RHIC), the Tevatron and the Large Hadron Collider (LHC) produce photonuclear and two-photon interactions at luminosities and energies beyond that accessible elsewhere; the LHC will reach a $\gamma p$ energy ten times that of the Hadron-Electron Ring Accelerator (HERA). Reactions as diverse as the production of anti-hydrogen, photoproduction of the $\rho^0$, transmutation of lead into bismuth and excitation of collective nuclear resonances have already been studied. At the LHC, UPCs can study many types of `new physics.'

All-order resummation of soft gluons for transverse energy-energy correlators in diffractive dijet production demonstrates sensitivity of acoplanarity to diffractive TMDs.
Simulated spin-interference patterns in ρ(1450)→4π decays give a distinct azimuthal modulation for the π(1300)π channel, allowing its branching fraction to be extracted.
ALICE reports new rapidity-differential cross sections for coherent J/ψ and ψ(2S) photoproduction and exclusive dimuons in forward rapidity UPC Pb-Pb collisions at 5.36 TeV, showing nuclear shadowing ratios of approximately 0.76 and 0.71.
Color dipole calculations of the ratio of exclusive vector meson to inclusive jet/hadron photoproduction cross sections in UPC pA and AA collisions at LHC Run 4, including the double ratio R_UPC proposed for saturation studies.
Improved tensor-pomeron model for π⁺π⁻ photoproduction and central exclusive production in pp collisions that accounts for different subenergies in the Drell-Söding contribution and yields larger cross sections with more skewed ρ⁰ lineshape.
