Beyond Discontinuities: Cosmological WFCs and the Supersymmetric Orthogonal Grassmannian

Yu-tin Huang, Chia-Kai Kuo, Yohan Liu +1

We construct an supersymmetric Grassmannian representation of tree-level wavefunction coefficients (WFCs) by combining Grassmannian representations of energy discont…

Notes on off-shell conformal integrals and correlation functions at five points

Chia-Kai Kuo, Qinglin Yang

We study five-point off-shell conformal integrals and the associated half-BPS correlation functions at two loops in the 't Hooft coupling expansion of maximally supersymmetric Yang…

BDS ansatz in ABJM via scaffolding triangulations

Yu-tin Huang, Chia-Kai Kuo, Chi Zhang

In this work, we analyze the infrared divergence of two-loop amplitudes at arbitrary multiplicity in three-dimensional Chern-Simons matter theory. We introduce the…

Leading singularities and chambers of Correlahedron

Song He, Yu-tin Huang, Chia-Kai Kuo

In this paper, we explore the chamber dissection of the loop-geometry of Correlahedron, which encodes the loop integrand of four-point stress-energy correlators in planar $\mathcal…

All-loop geometry for four-point correlation functions

Song He, Yu-tin Huang, Chia-Kai Kuo

In this letter, we consider a positive geometry conjectured to encode the loop integrand of four-point stress-energy correlators in planar super Yang-Mills. Beginni…

The ABJM Amplituhedron

Song He, Yu-tin Huang, Chia-Kai Kuo

In this paper, we take a major step towards the construction and applications of an all-loop, all-multiplicity amplituhedron for three-dimensional planar Chern-Simo…

Emergent unitarity, all-loop cuts and integrations from the ABJM amplituhedron

Song He, Chia-Kai Kuo, Zhenjie Li +1

We elaborate on aspects of a new positive geometry proposed recently, which was conjectured to be the four-point amplituhedron for ABJM theory. We study generalized unitarity cuts…

The two-loop eight-point amplitude in ABJM theory

Song He, Yu-tin Huang, Chia-Kai Kuo +1

In this paper, we present the two-loop correction to scattering amplitudes in three-dimensional Chern-Simons matter theory. We use eight-point case as our main exam…

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…

The momentum amplituhedron of SYM and ABJM from twistor-string maps

Song He, Chia-Kai Kuo, Yao-Qi Zhang

We study remarkable connections between twistor-string formulas for tree amplitudes in SYM and ABJM, and the corresponding momentum amplituhedron in the k…

Dualities for Ising networks

Yu-tin Huang, Chia-Kai Kuo, Congkao Wen

In this note, we study the equivalence between planar Ising networks and cells in the positive orthogonal Grassmannian. We present a microscopic construction based on amalgamation,…
