This process computes the contribution of light-quark loops
|
|
to the process $gg \to \gamma\gamma$. It is calculable at leading LO
|
|
and next-to-leading order NLO.
|
|
The calculation and a phenomenological analysis are described
|
|
in Ref.~\cite{Campbell:2016yrh}.
|
|
This process includes the one-loop gluon-gluon contribution as
|
|
given in ref.~\cite{Bern:2002jx}.
