Conformal bootstrap in Mellin space from GG systems
Koushik Ray
A simple scheme to express the Mellin transform of -dimensional Euclidean conformal bootstrap equation is presented by relating conformal blocks to a Gauss-Grassmann (GG) system…
Minkowski Space holography and Radon transform
Samrat Bhowmick, Koushik Ray
We relate a free scalar field in the Minkowski spacetime with a scalar field with a certain scaling dimension on a sphere of codimension two. This is realised by first performing a…
On entropy and complexity of coherent states
Koushik Ray
Consanguinity of entropy and complexity is pointed out through the example of coherent states of the group $SL(d+1,\C)$. Both are obtained from the Kähler potential of the underlyi…
Conformal integrals in all dimensions as GKZ hypergeometric functions and Clifford groups
Aritra Pal, Koushik Ray
Euclidean conformal integrals for an arbitrary number of points in any dimension are evaluated. Conformal transformations in the Euclidean space can be formulated as the Moebius gr…
Towards a categorification of scattering amplitudes
Severin Barmeier, Prafulla Oak, Aritra Pal +2
Categorification of scattering amplitudes for planar Feynman diagrams in scalar field theories with a polynomial potential is reported. Amplitudes for cubic theories are directly w…
Conformal Integrals in four dimensions
Aritra Pal, Koushik Ray
We obtain analytic expressions of four-dimensional Euclidean -point conformal integrals for arbitrary by solving a Lauricella-like system of differential equations derived e…
