Abstract: We show that Feynman integrals occurring in standard quantum field theories or perturbative worldline approaches to the scattering of real black holes are related to periods of Calabi-Yau varieties of various dimensions. After defining what mathematical properties a Calabi-Yau period motive has, we explain how the applications of the latter lead to an efficient analytic evaluation of the Feynman integrals in dimensional regularisation.
