Supergravity limit of genus two modular graph functions in the worldline formalism
We consider the contributions up to the D10R4 terms in the low momentum expansion of the two loop four graviton amplitude in maximal supergravity that arise in the field theory limit of genus two modular graph functions that result from the low momentum expansion of the four graviton amplitude in to...
