Abstract

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