Adjacency for scattering amplitudes from the Gröbner fan
L. Bossinger, J. M. Drummond, R. Glew
Scattering amplitudes in planar super Yang-Mills theory exhibit singularities which reflect various aspects of the cluster algebras associated to the Grassmannians…
One-loop string corrections for AdS Kaluza-Klein amplitudes
J. M. Drummond, R. Glew, H. Paul
We discuss the string corrections to one-loop amplitudes in AdSS, focussing on their expressions in Mellin space. We present the leading corrections to the…
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…
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…
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…
First detection of the outer edge of an AGN accretion disc: Very fast multiband optical variability of NGC 4395 with GTC/HiPERCAM and LT/IO:O
I. M. McHardy, M. Beard, E. Breedt +11
We present fast (~200s sampling) ugriz photometry of the low mass AGN NGC 4395 with the Liverpool Telescope, followed by very fast (3s sampling) us, gs, rs, is and zs simultaneous…
