All-multiplicity monodromy and KLT relations for AdS string integrals
Maria Nocchi, Rodrigo Schmidt Pitombo, Aurélie Strömholm Sangaré +1
We propose and study all-multiplicity building blocks for tree-level string amplitudes in AdS. These are worldsheet integrals obtained by dressing the corresponding flat-space disc…
Mass-Flow Invariance of -Cohomology in BMN Matrix Quantum Mechanics
Chi-Ming Chang, Zhengyuan Du, Sarthak Duary +2
We study the dependence of the dynamical supercharges of BMN matrix quantum mechanics on the mass parameter . Taking the -derivative at fixed canonical matrix variables, we s…
Notes on flat-space limit of holographic defect correlators in position space
Qi Chen, Yi-Xiao Tao, Xinan Zhou
We study the large AdS radius limit of correlation functions in holographic defect CFTs. For two-point functions of operators inserted away from the defect, we derive a position sp…
Systematic approach to -loop planar integrands from the classical equation of motion
Yi-Xiao Tao
In this paper, we present a recursive method for -loop planar integrands in colored quantum field theories. We start with the classical equation of motion and then pick out t…
Multivariate hypergeometric solutions of cosmological (dS) correlators by -form differential equations
Jiaqi Chen, Bo Feng, Yi-Xiao Tao
In this paper, we give the analytic expression for the homogeneous part of solutions of arbitrary tree-level cosmological correlators, including massive propagators and time-deriva…
The Aharony-Bergman-Jafferis-Maldacena theory on a circle
Yi-Xiao Tao
In this work, we bootstrap the 4-point correlators on the 1D celestial circle using 3D symmetries in the Aharony-Bergman-Jafferis-Maldacena theory as constraints. We find that the…
The off-shell expansion relation of the Yang-Mills scalar theory
Yi-Xiao Tao, Konglong Wu
In this work, we investigated the off-shell expansion relation of the Yang-Mills scalar theory. We explicitly showed that the single-trace Berends-Giele currents in the Yang-Mills…
Celestial self-dual Yang-Mills theory: a new formula and the OPE limit
Pratik Chattopadhyay, Yi-Xiao Tao
Celestial holography is a new way to understand flat-space amplitudes. Self-dual theories, due to their nice properties, are good subjects to study celestial holography. In this pa…
Celestial Berends-Giele current
Yi-Xiao Tao
Celestial amplitude plays an important role in the understanding of holography. Computing celestial amplitudes by recursion can deepen our understanding of the structure of celesti…
Notes on weight-shifting operators and unifying relations for cosmological correlators
Qi Chen, Yi-Xiao Tao
We seek the inverse formulas for the cosmological unifying relation between gluons and conformally coupled scalars. We demonstrate that the weight-shifting operators derived from t…
Decoding stringy near-supersymmetric black holes
Chi-Ming Chang, Li Feng, Ying-Hsuan Lin +1
Building on the recent discovery of the first candidate black hole operator in super-Yang-Mills, we explore the near-supersymmetric aspects of the theory that captu…
Differential Operators and Unifying Relations for 1-loop Feynman Integrands from Berends-Giele Currents
Qi Chen, Yi-Xiao Tao
Our work focuses on utilizing the Berends-Giele currents to construct differential operators and unifying relations for 1-loop Feynman integrands. We successfully reproduce the kno…
A Type of Unifying Relation in (A)dS Spacetime
Yi-Xiao Tao, Qi Chen
Unifying relations of amplitudes are elegant results in flat spacetime, but the research on these in (A)dS case is not very rich. In this paper, we discuss a type of unifying relat…
