The Tutte polynomial determines the linear coefficient of the Ehrhart polynomial
Erik Panzer
We prove a formula for the linear coefficient of the Ehrhart polynomial in terms of the Tutte polynomial. Furthermore, we characterize the matroids that extremize this Ehrhart coef…
Feynman symmetries of the Martin and invariants of regular graphs
Erik Panzer, Karen Yeats
For every regular graph, we define a sequence of integers, using the recursion of the Martin polynomial. This sequence counts spanning tree partitions and constitutes the diagonal…
Hierarchies in relative Picard-Lefschetz theory
Marko Berghoff, Erik Panzer
We prove a relative version of the Picard-Lefschetz theorem, describing the variation of relative homology groups in the fibers of a smoot…
Glue-and-Cut at Five Loops
Alessandro Georgoudis, Vasco Gonçalves, Erik Panzer +3
We compute epsilon-expansions around 4 dimensions of a complete set of master integrals for momentum space five-loop massless propagator integrals in dimensional regularization, up…
Four-loop collinear anomalous dimensions in QCD and super Yang-Mills
Bakul Agarwal, Andreas von Manteuffel, Erik Panzer +1
We calculate the collinear anomalous dimensions in massless four-loop QCD and supersymmetric Yang-Mills theory from the infrared poles of vertex form factors. We…
Two-loop mixed QCD-EW corrections to
Marco Bonetti, Erik Panzer, Vladimir A. Smirnov +1
We compute the two-loop mixed QCD-Electroweak (QCD-EW) corrections to the production of a Higgs boson and a gluon in gluon fusion. The relevant four-point functions with internal m…
