Triggering on light-by-light scattering in the ATLAS experiment
Based on lead-lead (Pb+Pb) collision data from 2015, the first evidence of light-by-light (LbyL) scattering in heavy-ion collisions was reported by the ATLAS Collaboration. The signature of LbyL scattering consists of two low-$p_\mathrm{T}$ photons and the absence of any other activity in the detect...
