B-type anomaly coefficients for the D3-D5 domain wall
Marius de Leeuw, Charlotte Kristjansen, Georgios Linardopoulos +1
We compute type-B Weyl anomaly coefficients for the domain wall version of N = 4 SYM that is holographically dual to the D3-D5 probe-brane system with flux. Our starting point is t…
Functions Beyond Multiple Polylogarithms for Precision Collider Physics
Jacob L. Bourjaily, Johannes Broedel, Ekta Chaubey +14
Feynman diagrams constitute one of the essential ingredients for making precision predictions for collider experiments. Yet, while the simplest Feynman diagrams can be evaluated in…
Direct Integration for Multi-leg Amplitudes: Tips, Tricks, and When They Fail
Jacob L. Bourjaily, Yang-Hui He, Andrew J. McLeod +5
Direct hyperlogarithmic integration offers a strong alternative to differential equation methods for Feynman integration, particularly for multi-particle diagrams. We review a vari…
Cuts and Isogenies
Hjalte Frellesvig, Cristian Vergu, Matthias Volk +1
We consider the genus-one curves which arise in the cuts of the sunrise and in the elliptic double-box Feynman integrals. We compute and compare invariants of these curves in a num…
Wilson lines in AdS/dCFT
Sara Bonansea, Khalil Idiab, Charlotte Kristjansen +1
We consider the expectation value of Wilson lines in two defect versions of N = 4 SYM, both with supersymmetry completely broken, where one is described in terms of an integrable b…
Traintrack Calabi-Yaus from Twistor Geometry
Cristian Vergu, Matthias Volk
We describe the geometry of the leading singularity locus of the traintrack integral family directly in momentum twistor space. For the two-loop case, known as the elliptic double…
Conformally Regulated Direct Integration of the Two-Loop Heptagon Remainder
Jacob L. Bourjaily, Matthias Volk, Matt von Hippel
We reproduce the two-loop seven-point remainder function in planar, maximally supersymmetric Yang-Mills theory by direct integration of conformally-regulated chiral integrands. The…
A Quantum Framework for AdS/dCFT through Fuzzy Spherical Harmonics on
Aleix Gimenez-Grau, Charlotte Kristjansen, Matthias Volk +1
We consider a non-supersymmetric domain-wall version of SYM theory where five out of the six scalar fields have non-zero classical values on one side of a wall of…
Rooting Out Letters: Octagonal Symbol Alphabets and Algebraic Number Theory
Jacob L. Bourjaily, Andrew J. McLeod, Cristian Vergu +3
It is widely expected that NMHV amplitudes in planar, maximally supersymmetric Yang-Mills theory require symbol letters that are not rationally expressible in terms of momentum-twi…
Embedding Feynman Integral (Calabi-Yau) Geometries in Weighted Projective Space
Jacob L. Bourjaily, Andrew J. McLeod, Cristian Vergu +3
It has recently been demonstrated that Feynman integrals relevant to a wide range of perturbative quantum field theories involve periods of Calabi-Yaus of arbitrarily large dimensi…
A Quantum Check of Non-Supersymmetric AdS/dCFT
Aleix Gimenez Grau, Charlotte Kristjansen, Matthias Volk +1
Via a challenging field-theory computation, we confirm a supergravity prediction for the non-supersymmetric D3-D7 probe-brane system with probe geometry AdS_4 x S^2 x S^2, stabiliz…
