Covariant color-kinematics duality, Hopf algebras and permutohedra
Qu Cao, Jin Dong, Song He +1
Based on the covariant color-kinematics duality, we investigate combinatorial and algebraic structures underlying their Bern-Carrasco-Johansson (BCJ) numerators of tree-level ampli…
Reduction of General One-loop Integrals Using Auxiliary Vector
Bo Feng, Tingfei Li, Hongbin Wang +1
As a key method to deal with loop integrals, Integration-By-Parts (IBP) method can be used to do reduction as well as establish the differential equations for master integrals. How…
One-loop diagrams with quadratic propagators from the worldsheet
Bo Feng, Song He, Yong Zhang +1
It is well known that forward limits of tree-level amplitudes (and those trivalent diagrams they consist of) produce one-loop amplitudes and trivalent diagrams with propagators lin…
All-Loop Four-Point Aharony-Bergman-Jafferis-Maldacena Amplitudes from Dimensional Reduction of the Amplituhedron
Song He, Chia-Kai Kuo, Zhenjie Li +1
We define a new geometry obtained from the all-loop amplituhedron in SYM by reducing its four-dimensional external and loop momenta to three dimensions. Focusing on th…
