Tidal effects on radiation in gravitational shockwave collisions
Isabelle Blackstad, Himanshu Raj, Raju Venugopalan
We compute high frequency gravitational wave radiation in shockwave collisions of a light mass compact object with energy off a heavy compact object (black hole) with energy…
QCD-Gravity double-copy in the Regge regime: shock wave propagators
Himanshu Raj, Raju Venugopalan
In recent work, we demonstrated a double-copy relation between inclusive gluon radiation in shock wave collisions of ultrarelativistic nuclei and inclusive graviton radiation in tr…
Wee partons in QCD and gravity: double copy and universality
Himanshu Raj, Raju Venugopalan
We discuss a quantitative "double copy" between radiation from shockwave collisions in Einstein gravity and in QCD. The correspondence extends to amplitudes in Reg…
Gravitational wave double copy of radiation from gluon shockwave collisions
Himanshu Raj, Raju Venugopalan
In a recent paper, we showed that the gravitational wave spectrum from trans-Planckian shockwave scattering in Einstein gravity is determined by the gravitational Lipatov vertex ex…
Universal features of scattering in QCD and gravity from shockwave collisions
Himanshu Raj, Raju Venugopalan
A remarkable double copy relation of Einstein gravity to QCD in Regge asymptotics is , where is the gravitational Lipatov vertex in t…
Integrated Correlators in SYM via Spectral Theory
Hynek Paul, Eric Perlmutter, Himanshu Raj
We perform a systematic study of integrated four-point functions of half-BPS operators in four-dimensional super Yang-Mills theory with gauge group . These o…
M-theory on at 1-loop and beyond
Luis F. Alday, Shai M. Chester, Himanshu Raj
We study graviton scattering on , which is dual to the stress tensor multiplet four-point function in the maximally supersymmetric 3d ABJM…
ABJM at Strong Coupling from M-theory, Localization, and Lorentzian Inversion
Luis F. Alday, Shai M. Chester, Himanshu Raj
We study the stress tensor multiplet four-point function in the 3d maximally supersymmetric ABJ(M) theory with Chern-Simons level , which in the large limit is holographic…
Complex Sachdev-Ye-Kitaev model in the double scaling limit
Micha Berkooz, Vladimir Narovlansky, Himanshu Raj
We solve for the exact energy spectrum, 2-point and 4-point functions of the complex SYK model, in the double scaling limit at all energy scales. This model has a global sym…
6d (2,0) and M-theory at 1-loop
Luis F. Alday, Shai M. Chester, Himanshu Raj
We study the stress tensor multiplet four-point function in the 6d maximally supersymmetric and theories, which have no Lagrangian description, but in the l…

Chethan Krishnan, Himanshu Raj, P. N. Bala Subramanian
We construct general asymptotically Klebanov-Strassler solutions of a five dimensional truncation of IIB supergravity…
Mass deformations of 5d SCFTs via holography
Michael Gutperle, Justin Kaidi, Himanshu Raj
Using six-dimensional Euclidean gauged supergravity we construct a holographic renormalization group flow for a CFT on . Numerical solutions to the BPS equations are ob…
Janus solutions in six-dimensional gauged supergravity
Michael Gutperle, Justin Kaidi, Himanshu Raj
Motivated by an analysis of the sub-superalgebras of the five-dimensional superconformal algebra , we search for the holographic duals to co-dimension one superconformal defe…
On non-supersymmetric conformal manifolds: field theory and holography
Vladimir Bashmakov, Matteo Bertolini, Himanshu Raj
We discuss the constraints that a conformal field theory should enjoy to admit exactly marginal deformations, i.e. to be part of a conformal manifold. In particular, using tools fr…
A note on sphere free energy of -form gauge theory and Hodge duality
Himanshu Raj
We consider a free -form gauge theory on a -dimensional sphere of radius and calculate its free energy. We perform the calculation for generic values of and obtain th…
Broken current anomalous dimensions, conformal manifolds and RG flows
Vladimir Bashmakov, Matteo Bertolini, Himanshu Raj
We consider deformations of a conformal field theory that explicitly break some global symmetries of the theory. If the deformed theory is still a conformal field theory, one can e…
Scalar Multiplet Recombination at Large N and Holography
Vladimir Bashmakov, Matteo Bertolini, Lorenzo Di Pietro +1
We consider the coupling of a free scalar to a single-trace operator of a large N CFT in d dimensions. This is equivalent to a double-trace deformation coupling two primary operato…

Working within a five-dimensional consistent truncation of type IIB supergravity dimensionally reduced on , we consider supersymmetry breaking solutions with the asymptoti…
