Planar Matrices and Arrays of Feynman Diagrams
Freddy Cachazo, Alfredo Guevara, Bruno Umbert +1
Very recently planar collections of Feynman diagrams were proposed by Borges and one of the authors as the natural generalization of Feynman diagrams for the computation of b…
On Positive Geometry and Scattering Forms for Matter Particles
Aidan Herderschee, Song He, Fei Teng +1
We initiate the study of positive geometry and scattering forms for tree-level amplitudes with matter particles in the (anti-)fundamental representation of the color/flavor group.…
Bulk Fermi surface of the layered superconductor TaSe3 with three-dimensional strong topological insulator state
Wei Xia, Xianbiao Shi, Yong Zhang +14
High magnetic field transport measurements and ab initio calculations on the layered superconductor TaSe3 have provided compelling evidences for the existence of a three-dimensiona…
Singular Solutions in Soft Limits
Freddy Cachazo, Bruno Umbert, Yong Zhang
A generalization of the scattering equations on , the configuration space of points on , to higher dimensional projective spaces was recently introduced…
String Correlators: Recursive Expansion, Integration-by-Parts and Scattering Equations
Song He, Fei Teng, Yong Zhang
We further elaborate on the general construction proposed in arXiv:1812.03369, which connects, via tree-level double copy, massless string amplitudes with color-ordered QFT amplitu…
