Rigid supersymmetry on Three-Manifolds
📍 London
Cyril Closset
(Weizmann Institute)
Abstract:
I will explain how to put three-dimensional supersymmetric theories on curved three-manifolds preserving some supersymmetry. I will discuss some physical implications of this method, including an exact formula for the two-point function of the energy-momentum tensor in 3d N=2 superconformal theories.

On Non-Abelian T-Dualities and AdS Geometries
Daniel Thompson
(Solvay Institutes)
Abstract:
I will explain how the notion of T-duality can be generalised to
the case of a non-abelian isometry group and applied as a solution
generating symmetry to type II supergravity backgrounds involving RR flux.
I will show some novel mappings between IIB and (massive) IIA supergravity
and apply the technique to backgrounds of importance in the context of the
gauge/gravity correspondence. In particular we will find some surprising
connections between \(AdS_5\times S^5\) and the geometry proposed by Gaiotto
and Maldacena as dual to certain N=2 SCFT's and between the Klebanov-Witten
background (\(AdS_5 \times T^{1,1}\)) and the geometries discussed already in
this seminar series by Wecht as dual to certain N=1 SCFT's. Time
permitting I will describe some recent developments relating to the gravity
duals of cascading gauge theories.

A Modern look at the Regge limit in QCD, SUSY and gravity
Agustin Sabio Vera
(Universidad Autonoma de Madrid / CERN)
Abstract:
A pedagogical introduction to the Regge limit of scattering amplitudes
will be given. Its role in collider physics will be explained, together
with its connections to integrability in QCD and SUSY theories. We will
finish with a discussion on graviton scattering at high energies.
