Aspects of Weyl Supergravity / Ferrara, Sergio (CERN ; Frascati ; UCLA) ; Kehagias, Alex (Natl. Tech. U., Athens) ; Lüst, Dieter (CERN ; Munich U., ASC ; Munich, Max Planck Inst.)
In this paper we study the spectrum of all conformal, ${\cal N}$-extended supergravities (${\cal N}=1,2,3,4$) in four space-time dimensions. When these theories are obtained as massless limit of Einstein plus Weyl$^2$supergravity, the appropriate counting of the enhanced gauge symmetries allow us to derive the massless spectrum which consist of a dipole ghost graviton multiplet, a ${\cal N}$-fold tripole ghost gravitino, the third state belonging to a spin 3/2 multiplet and a residual vector multiplet present for non-maximal ${\cal N}<4$ theories.

Bimetric, Conformal Supergravity and its Superstring Embedding / Ferrara, Sergio (CERN ; Frascati ; UCLA) ; Kehagias, Alex (Natl. Tech. U., Athens) ; Lüst, Dieter (CERN ; Munich U., ASC ; Munich, Max Planck Inst.)
We discuss the connection between Weyl$^2$ supergravity and superstrings and further discuss holography between 4-dimensional, ${\cal N}=4$ superconformal Weyl$^2$ supergravity and ${\cal N}=8$, higher spin-four theory on $AdS_5$. The Weyl$^2$ plus Einstein supergravity theory is a special kind of a bimetric gravity theory and consists of a massless graviton multiplet plus an additional massive spin-two supermultiplet. [...]

Bootstrapping Mixed Correlators in 4D $\mathcal{N}=1$ SCFTs / Li, Daliang (Johns Hopkins U.) ; Meltzer, David (Yale U.) ; Stergiou, Andreas (Yale U. ; CERN)
The numerical conformal bootstrap is used to study mixed correlators in $\mathcal{N}=1$ superconformal field theories (SCFTs) in $d=4$ spacetime dimensions. Systems of four-point functions involving scalar chiral and real operators are analyzed, including the case where the scalar real operator is the zero component of a global conserved current multiplet.

Double logarithms in ${\cal N} \geq 4$ supergravity: weak gravity and Shapiro's time delay / Sabio Vera, Agustín (CERN ; Madrid, IFT ; Madrid, Autonoma U.)
A study of the double logarithmic in the center-of-mass energy, $s$, contributions to the four-graviton scattering amplitude is presented for four-dimensional ${\cal N} \geq 4$ supergravities. This includes a novel representation for the coefficients of the perturbative expansion based on exactly solvable recurrences. [...]

On the Kähler-Hodge structure of superconformal manifolds / Niarchos, Vasilis (Crete U.) ; Papadodimas, Kyriakos (CERN)
We show that conformal manifolds in $d\geq 3$ conformal field theories with at least 4 supercharges are Kähler-Hodge, thus extending to 3d ${\cal N}=2$ and 4d ${\cal N}=1$ similar results previously derived for 4d ${\cal N}=2$ and ${\cal N}=4$ and various types of 2d SCFTs. Conformal manifolds in SCFTs are equipped with a holomorphic line bundle ${\cal L}$, which encodes the operator mixing of supercharges under marginal deformations. [...]

Supersymmetric gauged matrix models from dimensional reduction on a sphere / Closset, Cyril (CERN) ; Ghim, Dongwook (Seoul Natl. U., Dept. Phys. Astron.) ; Seong, Rak-Kyeong (Tsinghua U., Beijing)
It was recently proposed that N=1 supersymmetric gauged matrix models have a duality of order four - that is, a quadrality - reminiscent of infrared dualities of SQCD theories in higher dimensions. In this note, we show that the zero-dimensional quadrality proposal can be infered from the two-dimensional Gadde-Gukov-Putrov triality. [...]

${\cal R}^2$ Supergravity / Ferrara, Sergio (UCLA ; CERN ; Frascati) ; Kehagias, Alex (Natl. Tech. U., Athens) ; Porrati, Massimo (CERN ; New York U., CCPP)
We formulate $R^2$ pure supergravity as a scale invariant theory built only in terms of superfields describing the geometry of curved superspace. The standard supergravity duals are obtained in both "old" and "new" minimal formulations of auxiliary fields. [...]

The Supercurrent and Einstein equations in the Superconformal formulation / Ferrara, Sergio (CERN ; UCLA ; Frascati) ; Samsonyan, Marine (CERN) ; Tournoy, Magnus (Leuven U.) ; Van Proeyen, Antoine (Leuven U.)
We give a new expression for the supercurrent and its conservation in curved ${\cal N}=1$, $D=4$ superspace using the superconformal approach. The first component of the superfield, whose lowest component is the vector auxiliary field gives the (super)Einstein equations. [...]

A tale of two exponentiations in $ \mathcal{N} $ = 8 supergravity at subleading level / Di Vecchia, Paolo (Nordita ; Royal Inst. Tech., Stockholm ; Bohr Inst.) ; Naculich, Stephen G. (Bowdoin Coll.) ; Russo, Rodolfo (Queen Mary, U. of London) ; Veneziano, Gabriele (CERN ; College de France) ; White, Chris D. (Queen Mary, U. of London)
High-energy massless gravitational scattering in ${\cal N}=8$ supergravity was recently analyzed at leading level in the deflection angle, uncovering an interesting connection between exponentiation of infrared divergences in momentum space and the eikonal exponentiation in impact parameter space. Here we extend that analysis to the first non trivial sub-leading level in the deflection angle which, for massless external particles, implies going to two loops, i.e. [...]
