Title: 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 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 the three-loop case and check the results against the known results for special mass values.
