Amplitudes at strong coupling as hyperkähler scalars
Hadleigh Frost, Ömer Gürdogan, Lionel Mason
Alday & Maldacena conjectured an equivalence between string amplitudes in AdS and null polygonal Wilson loops in planar super-Yang-Mills (SYM). At st…
Antipodal Self-Duality for a Four-Particle Form Factor
Lance J. Dixon, Ömer Gürdoğan, Yu-Ting Liu +2
We bootstrap the symbol of the maximal-helicity-violating four-particle form factor for the chiral part of the stress-tensor supermultiplet in planar super-Yang-Mil…
Bootstrapping a Stress-Tensor Form Factor through Eight Loops
Lance J. Dixon, Omer Gurdogan, Andrew J. McLeod +1
We bootstrap the three-point form factor of the chiral stress-tensor multiplet in planar supersymmetric Yang-Mills theory at six, seven, and eight loops, using boun…
Folding Amplitudes into Form Factors: An Antipodal Duality
Lance J. Dixon, Omer Gurdogan, Andrew J. McLeod +1
We observe that the three-gluon form factor of the chiral part of the stress-tensor multiplet in planar super-Yang-Mills theory is dual to the six-gluon MHV amplitu…
Tropical fans, scattering equations and amplitudes
James Drummond, Jack Foster, Ömer Gürdoğan +1
We describe a family of tropical fans related to Grassmannian cluster algebras. These fans are related to the kinematic space of massless scattering processes in a number of ways.…
Algebraic singularities of scattering amplitudes from tropical geometry
James Drummond, Jack Foster, Ömer Gürdoğan +1
We address the appearance of algebraic singularities in the symbol alphabet of scattering amplitudes in the context of planar super Yang-Mills theory. We argue that…
Tropical Grassmannians, cluster algebras and scattering amplitudes
James Drummond, Jack Foster, Ömer Gürdoğan +1
We provide a cluster-algebraic approach to the computation of the recently introduced generalised biadjoint scalar amplitudes related to Grassmannians . A finite clu…
Cluster adjacency beyond MHV
James Drummond, Jack Foster, Omer Gurdogan
We explore further the notion of cluster adjacency, focussing on non-MHV amplitudes. We extend the notion of adjacency to the BCFW decomposition of tree-level amplitudes. Adjacency…
Cluster adjacency properties of scattering amplitudes
James Drummond, Jack Foster, Omer Gurdogan
We conjecture a new set of analytic relations for scattering amplitudes in planar N=4 super Yang-Mills theory. They generalise the Steinmann relations and are expressed in terms of…
Two-loop Sudakov Form Factor in ABJM
Andreas Brandhuber, Omer Gurdogan, Dimitrios Korres +2
We compute the two-loop Sudakov form factor in three-dimensional N=6 superconformal Chern-Simons theory, using generalised unitarity. As an intermediate step, we derive the non-pla…
Harmony of Super Form Factors
Andreas Brandhuber, Omer Gurdogan, Robert Mooney +2
In this paper we continue our systematic study of form factors of half-BPS operators in N=4 super Yang-Mills. In particular, we extend various techniques known for amplitudes to th…
Walking solutions in the string background dual to N=1 SQCD-like theories
Omer Can Gurdogan
A new solution in the string background dual to N=1 SQCD-like theories is presented. The gauge coupling in this solution has walking property. The Wilson loop calculations show tha…
