The Hydrotope in the Water-Wave Action
Qu Cao, Song He, Jirong Jing +1
The Hydrotope gives a geometric representation of tree-level water-wave amplitudes with two negative spatial momenta as the volume of a hyperplane slice of a box. We trace the orig…
Tropical and Stringy Integrals for In-In Correlators
Song He, Xiang Li, Yong-Xiang Su +1
We introduce tropical and stringy integrals for fixed-graph contributions to cosmological in-in correlators of conformally coupled scalars. The full-time representation factorizes…
Planar loop integrands from cuts in dimensions
Fan Zhu, Song He, Zhenqi Han
We present a direct reconstruction formula for planar loop integrands from -dimensional generalized unitarity cuts in any colored theory. The reconstruction combinatorics is sep…
Bootstrapping Giant Graviton Correlators
Song He, Canxin Shi, Yichao Tang +1
We develop bootstrap methods for mixed heavy-light four-point correlators in super-Yang--Mills theory at large , where …
Loop-Level Double Copy Relations from Forward Limits
Qu Cao, Song He, Yong Zhang +1
We study double copy relations for loop integrands in gauge theories and gravity based on their constructions from single cuts, which are in turn obtained from forward limits of lo…
A Hidden Permutation Symmetry of Squared Amplitudes in ABJM Theory
Song He, Canxin Shi, Yichao Tang +1
We define the square amplitudes in planar Aharony-Bergman-Jafferis-Maldacena theory (ABJM), analogous to that in super-Yang-Mills theory (SYM). Surprisingly, the…
Superstring amplitudes meet surfaceology
Qu Cao, Jin Dong, Song He +1
We reformulate tree-level amplitudes in open superstring theory (type-I) in terms of stringy Tr amplitudes with various kinematical shifts in the "curve-integral" formulatio…
The Four-Point Correlator of Planar sYM at Twelve Loops
Jacob L. Bourjaily, Song He, Canxin Shi +1
We determine the 4-point correlation function and amplitude in planar, maximally supersymmetric Yang-Mills theory to 12 loops. We find that the recently-introduced 'double-triangle…
On one-loop amplitudes in gauge theories
Qu Cao, Jin Dong, Song He +1
We propose a new ``universal expansion" for one-loop amplitudes with arbitrary number of gluons in dimensions, which holds for general gauge theories with gluons/fermions/scala…
The Cusp Limit of Correlators and A New Graphical Bootstrap for Correlators/Amplitudes to Eleven Loops
Song He, Canxin Shi, Yichao Tang +1
We consider the universal behavior of half-BPS correlators in super-Yang-Mills in the cusp limit where two consecutive separations become lightl…
Surface Kinematics and "The" Yang-Mills Integrand
Nima Arkani-Hamed, Qu Cao, Jin Dong +2
It has been a long-standing challenge to define a canonical loop integrand for non-supersymmetric gluon scattering amplitudes in the planar limit. Naive integrands are inflicted wi…
Supergluon scattering in AdS: constructibility, spinning amplitudes, and new structures
Qu Cao, Song He, Xiang Li +1
We elaborate on a new recursive method proposed in arXiv:2312.15484 for computing tree-level -point supergluon amplitudes as well as those with one gluon, i.e., spinning amplitu…
On universal splittings of tree-level particle and string scattering amplitudes
Qu Cao, Jin Dong, Song He +2
In this paper, we study the newly discovered universal splitting behavior for tree-level scattering amplitudes of particles and strings~\cite{Cao:2024gln}: when a set of Mandelstam…
A universal splitting of string and particle scattering amplitudes
Qu Cao, Jin Dong, Song He +1
We propose a new splitting behavior of tree-level string/particle amplitudes for scalars, gluons and gravitons. We identify certain subspaces in the space of Mandelstam variables,…
Scalar-Scaffolded Gluons and the Combinatorial Origins of Yang-Mills Theory
Nima Arkani-Hamed, Qu Cao, Jin Dong +2
We present a new formulation for Yang-Mills scattering amplitudes in any number of dimensions and at any loop order, based on the same combinatorial and binary-geometric ideas in k…
Hidden zeros for particle/string amplitudes and the unity of colored scalars, pions and gluons
Nima Arkani-Hamed, Qu Cao, Jin Dong +2
Recent years have seen the emergence of a new understanding of scattering amplitudes in the simplest theory of colored scalar particles - the Tr theory - based on combinator…
Constructibility of AdS supergluon amplitudes
Qu Cao, Song He, Yichao Tang
We prove that all tree-level -point supergluon (scalar) amplitudes in AdS can be recursively constructed, using factorization and flat-space limit. Our method is greatly fac…
