Cosmological Correlators in Gauge Theory and Gravity from EAdS
Md. Abhishek, Charlotte Sleight, Massimo Taronna
In this work we examine in more detail the map between late-time correlators in de Sitter space and boundary correlators in Euclidean anti-de Sitter space, elaborating on the gener…
Looking for the Higgs Branch of 4D Rank 1 SCFTs
Md. Abhishek, Sachin Grover, Dileep P. Jatkar +1
The Schur index of the Higgs branch of 4-dimensional SCFTs is related to the spectrum of non-unitary 2-dimensional CFTs. The rank 1 case has been shown to lead to t…
On-shell functions on the Coulomb branch of SYM
Md. Abhishek, Subramanya Hegde, Dileep P. Jatkar +2
We study on-shell functions in the kinematic space for the Coulomb branch of SYM. We construct BCFW bridges that help us build bigger on-shell functions. As a conse…
Loop Amplitudes in the Coulomb Branch of Super-Yang-Mills Theory
Md. Abhishek, Subramanya Hegde, Dileep P. Jatkar +2
We study four point planar loop amplitudes at an arbitrary point in the Coulomb branch of super-Yang-Mills theory. We study two particle unitary cuts up to four loo…
Scattering Amplitudes and BCFW in Theory
Md. Abhishek, Subramanya Hegde, Dileep P. Jatkar +1
We use massive spinor helicity formalism to study scattering amplitudes in super-Yang-Mills theory in four dimensions. We compute the amplitudes at an arbitrary p…
One-loop integrand from generalised scattering equations
Md. Abhishek, Subramanya Hegde, Arnab Priya Saha
Generalised bi-adjoint scalar amplitudes, obtained from integrations over moduli space of punctured , are novel extensions of the CHY formalism. These amplitudes…
Double Soft Theorem for Generalised Biadjoint Scalar Amplitudes
Md. Abhishek, Subramanya Hegde, Dileep P. Jatkar +1
We study double soft theorem for the generalised biadjoint scalar field theory whose amplitudes are computed in terms of punctures on . We find that whenever the…
