International audience ; Light-by-light (LbyL) scattering, γγ → γγ, is a rare Standard Model(SM) process, also proposed as a sensitive channel to study physics beyondthe SM. In these proceedings, we perform a statistical combination of existingγγ → γγ cross section measurements at the LHC with the aim ofchecking the consistency with different SM predictions. Using a simplified set of assumptions, we find the averaged result of 115 ± 19 nb, consistentwith SM predictions within two standard deviations. For the first time,we also consider the contribution from the ηb(1S) meson production to thediphoton invariant mass distribution.
