Ultra-peripheral physics with ATLAS

In this talk we present recent results using ultraperipheral heavy ions collisions data collected by the ATLAS experiment in 2015 and 2018 at $\sqrt{\bar{s}_{N N}}=5.02 \mathrm{TeV}$. The talk cover light-by-light scattering fiducial and differential cross section measurement and search for axion li...

Sumario:In this talk we present recent results using ultraperipheral heavy ions collisions data collected by the ATLAS experiment in 2015 and 2018 at $\sqrt{\bar{s}_{N N}}=5.02 \mathrm{TeV}$. The talk cover light-by-light scattering fiducial and differential cross section measurement and search for axion like particles using combined 2015 and 2018 data-set, the exclusive dimuon production measurement using 2015 data and two-particle long-range azimuthal correlation measured in photonuclear collisions using $1.7 \mathrm{nb}^{-1}$ of data collected in 2018 which is compared with results obtained in proton-proton and proton-lead collisions for similar multiplicity ranges.
