We provide analytical estimates of the photon source properties and of the yield of secondary pairs, finding excellent agreement with full-scale 3D self-consistent particle-in-cell simulations that include quantum electrodynamics effects. Our results show that beam-beam collisions can be exploited as secondary sources of gamma rays and provide an alternative to beam-laser setups to probe quantum electrodynamics effects at the Schwinger limit.
