Light-by-light scattering in ultra-peripheral heavy-ion collisions at low diphoton masses

Mariola Klusek-Gawenda, Ronan McNulty, Rainer Schicker +1

We present a study of photon-photon scattering in the mass range $W_{\gamma \gamma }<5$ GeV. We extend earlier calculations of this cross section for $W_{\gamma \gamma }>$ 5 GeV into the low mass range…
