Degenerations of flat connections on Riemann surfaces
Mattia Biancotto, Eric D'Hoker, Axel Kleinschmidt +2
The integration kernels for polylogarithm functions on a compact Riemann surface of arbitrary genus are shown to close as the surface undergoes a non-separating degeneration to…
Quantum Gravity on AdSS from CFT: Bootstrapping
Francesco Aprile, Hynek Paul, Michele Santagata
We consider the simplest four-point scattering amplitude of tensor multiplets in six-dimensional (2,0) supergravity on AdSS. Using crossing symmetry and the c…
Surprising one-loop finiteness of 6D half-maximal supergravities
Yu-tin Huang, Henrik Johansson, Michele Santagata +1
In four dimensions, it has long been established that gravity coupled to matter exhibits ultraviolet divergences at one loop, irrespective of supersymmetry. Notably, the four-matte…
Simplicity of Mellin amplitudes for AdSS
F. Aprile, C. Behan, R. S. Pitombo +1
The spectrum of half-BPS single-particle operators of the D1-D5 system in the supergravity regime is dual to the spectrum of Kaluza-Klein modes of tensor and graviton multiplets in…
A formula for the block expansion in free CFTs and applications to SYM at strong coupling
F. Aprile, J. M. Drummond, P. J. Heslop +1
An explicit analytic formula is presented that computes the conformal (super-)block decomposition of any free scalar or half-BPS diagram in 1d, 2d or 4d CFTs, with various supersym…
Non-analytic terms of string amplitudes from partial waves
Yu-tin Huang, Hynek Paul, Michele Santagata
We describe a general formalism based on the partial-wave decomposition to compute the iterative -channel discontinuity of four-point amplitudes at any loop order. As an applica…
Hidden Conformal Symmetry in AdSS Beyond Tree Level
P. J. Heslop, A. E. Lipstein, M. Santagata
Correlators of a certain one-dimensional superconformal field theory dual to hypermultiplets in AdSS exhibit a hidden four-dimensional conformal symmetry which allows…
Genus-one open string amplitudes on AdSS from CFT
Hynek Paul, Michele Santagata
We bootstrap one-loop string corrections to the four-point function of half-BPS operators in a 4d SCFT with flavour group , dual to gluon scattering at genus…
The Veneziano amplitude in AdSS from an 8-dimensional effective action
R. Glew, M. Santagata
We study four-point functions of arbitrary half-BPS operators in a 4-dimensional SCFT with flavour group at genus-zero and strong 't Hooft coupling, corresp…
One-loop string amplitudes in AdSS: Mellin space and sphere splitting
F. Aprile, J. M. Drummond, R. Glew +1
We study string corrections to one-loop amplitudes of single-particle operators in . The tree-level correlators in supergravity enjoy an accidental 1…
BCJ relations in and the double-trace spectrum of super gluons
J. M. Drummond, R. Glew, M. Santagata
We revisit the four-point function of super gluons in in the spirit of the large formalism and show how the integrand of a generalised Mellin transform satis…
Two-particle spectrum of tensor multiplets coupled to gravity
Francesco Aprile, Michele Santagata
We study the spectrum of certain two-particle operators in the supergravity regime of the D1-D5 system, focussing on the four-point correlators of tensor multiplets on $AdS_3\times…
The Virasoro-Shapiro amplitude in AdSS and level splitting of 10d conformal symmetry
F. Aprile, J. M. Drummond, H. Paul +1
The genus zero contribution to the four-point correlator of half-BPS single-particle operators ${\cal O}_p…
Bootstrapping string theory on AdS
J. M. Drummond, H. Paul, M. Santagata
We make an ansatz for the Mellin representation of the four-point amplitude of half-BPS operators of arbitrary charges at order in an expansion around the superg…
