A high-precision result for a full-color three-loop three-point form factor in SYM
Xin Guan, Guanda Lin, Xiao Liu +2
We perform a high-precision computation of the three-loop three-point form factor of the stress-tensor supermultiplet in SYM. Both the leading-color and non-leading-co…
Double copy for tree-level form factors. Part II. Generalizations and special topics
Guanda Lin, Gang Yang
Both the Bern, Carrasco and Johansson (BCJ) and the Kawai, Lewellen and Tye (KLT) double-copy formalisms have been recently generalized to a class of scattering matrix elements (so…
Double copy for tree-level form factors. Part I. Foundations
Guanda Lin, Gang Yang
The double-copy construction for form factors was reported in our previous work, in which a novel mechanism of turning spurious poles in Yang-Mills theory into physical poles in gr…
Kinematic Hopf algebra for amplitudes and form factors
Gang Chen, Guanda Lin, Congkao Wen
We propose a kinematic algebra for the Bern-Carrasco-Johansson (BCJ) numerators of tree-level amplitudes and form factors in Yang-Mills theory coupled with bi-adjoint scalars. The…
New relations for tree-level form factors and scattering amplitudes
Jin Dong, Song He, Guanda Lin
We show that tree-level form factors with length-two operators in Yang-Mills-scalar (YMS) theory exhibit structures very similar to scattering amplitudes of gluons and scalars, whi…
Conservative Binary Dynamics with a Spinning Black Hole at from Scattering Amplitudes
Fernando Febres Cordero, Manfred Kraus, Guanda Lin +2
We compute the conservative two-body Hamiltonian of a compact binary system with a spinning black hole through to all orders in velocity, including linear and qu…
Full-color three-loop three-point form factors in N=4 SYM
Guanda Lin, Gang Yang, Siyuan Zhang
We present the detailed computation of full-color three-loop three-point form factors of both the stress-tensor supermultiplet and a length-three BPS operator in N=4 SYM. The integ…
Color-Kinematics Duality and Dual Conformal Symmetry for A Four-loop Form Factor in N=4 SYM
Guanda Lin, Gang Yang, Siyuan Zhang
We obtain the full-color four-loop three-point form factor of the stress-tensor supermultiplet in N=4 SYM, based on the color-kinematics (CK) duality and generalized unitarity meth…
Double Copy of Form Factors and Higgs Amplitudes: A mechanism of turning spurious poles in Yang-Mills into physical poles in gravity
Guanda Lin, Gang Yang
We extend the double copy picture of scattering amplitudes to a class of matrix elements (so-called form factors) that involve local gauge invariant operators. Both the Bern, Carra…
Three-loop color-kinematics duality: A 24-dimensional solution space induced by new generalized gauge transformations
Guanda Lin, Gang Yang, Siyuan Zhang
We obtain full-color three-loop three-point form factors of the stress-tensor supermultiplet and also of a length-3 half-BPS operator in N=4 SYM based on the color-kinematics duali…
Non-planar form factors of generic local operators via on-shell unitarity and color-kinematics duality
Guanda Lin, Gang Yang
Form factors, as quantities involving both local operators and asymptotic particle states, contain information of both the spectrum of operators and the on-shell amplitudes. So far…
