The l-loop banana amplitude from GKZ systems and relative Calabi-Yau periods

Abstract We use the GKZ description of periods and certain classes of relative periods on families of Barth-Nieto Calabi-Yau (l − 1)-folds in order to solve the l-loop banana amplitudes with their general mass dependence. As examples we compute the mass dependencies of the banana amplitudes up to th...
