This is the declaration of the GtoGGGSplitFun class.
This class is an abstract class which describes the common
part of the G->GGG splitting function for both Initial State
and Final State Radiation. It should factorize the common
expression at LO, a part the coupling constant which is
kept separated for I.S.R. and F.S.R. for systematics evaluation.
***LOOKHERE*** This class is currently kept empty; however, if you have to implement it, you should proceed similarly to the GtoGGSplitFun class.
