Analytic Structure of all Loop Banana Amplitudes

Kilian Bönisch, Fabian Fischbach, Albrecht Klemm +2

Using the Gelfand-Kapranov-Zelevinsk\uı system for the primitive cohomology of an infinite series of complete intersection Calabi-Yau manifolds, whose dimension is the loop order m…

Lost Chapters in CHL Black Holes: Untwisted Quarter-BPS Dyons in the $Z_{2}$ Model

Fabian Fischbach, Albrecht Klemm, Christoph Nega

Motivated by recent advances in Donaldson-Thomas theory, four-dimensional $N = 4$ string-string duality is examined in a reduced rank theory on a less studied BPS sector. I…

The $l$ -loop Banana Amplitude from GKZ Systems and relative Calabi-Yau Periods

Albrecht Klemm, Christoph Nega, Reza Safari

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 w…
