Complete solution of the LSZ Model via Topological Recursion
Johannes Branahl, Alexander Hock
We prove that the Langmann-Szabo-Zarembo (LSZ) model with quartic potential, a toy model for a quantum field theory on noncommutative spaces grasped as a complex matrix model, obey…
An irregular spectral curve for the generation of bipartite maps in topological recursion
Johannes Branahl, Alexander Hock
We derive an efficient way to obtain generating functions of bipartite maps of arbitrary genus and boundary length using a spectral curve as initial data for the framework of topol…
Genus one free energy contribution to the quartic Kontsevich model
Johannes Branahl, Alexander Hock
We prove a formula for the genus one free energy of the quartic Kontsevich model for arbitrary ramification by working out a boundary creation operator for blob…
From scalar fields on quantum spaces to blobbed topological recursion
Johannes Branahl, Harald Grosse, Alexander Hock +1
We review the construction of the -model on noncommutative geometries via exact solutions of Dyson-Schwinger equations and explain how this construction relates via (blobbed)…
Perturbative and Geometric Analysis of the Quartic Kontsevich Model
Johannes Branahl, Alexander Hock, Raimar Wulkenhaar
The analogue of Kontsevich's matrix Airy function, with the cubic potential replaced by a quartic term with the sa…
Blobbed topological recursion of the quartic Kontsevich model I: Loop equations and conjectures
Johannes Branahl, Alexander Hock, Raimar Wulkenhaar
We provide strong evidence for the conjecture that the analogue of Kontsevich's matrix Airy function, with the cubic potential replaced by a quartic term $\mathr…
SUSY-QCD corrected and Sommerfeld enhanced stau annihilation into heavy quarks with scheme and scale uncertainties
J. Branahl, J. Harz, B. Herrmann +3
We investigate stau-antistau annihilation into heavy quarks in the phenomenological Minimal Supersymmetric Standard Model within the DM@NLO project. We present the calculation of t…
