A Calabi-Yau-to-Curve Correspondence for Feynman Integrals
Hans Jockers, Sören Kotlewski, Pyry Kuusela +5
It has long been known that the maximal cut of the equal-mass four-loop banana integral is a period of a family of Calabi-Yau threefolds that depends on the kinematic variable $z=m…

Modular Calabi-Yau Fourfolds and Connections to M-Theory Fluxes
Hans Jockers, Sören Kotlewski, Pyry Kuusela
In this work, we study the local zeta functions of Calabi-Yau fourfolds. This is done by developing arithmetic deformation techniques to compute the factor of the zeta function tha…

On the Geometry of N=2 Minkowski Vacua of Gauged N=2 Supergravity Theories in Four Dimensions
Hans Jockers, Sören Kotlewski
Gauging isometries of four-dimensional N=2 supergravity theories yields an N=2 supersymmetric theory with a scalar potential. In this note, we study the well-known constraints for…
