Gravity dual for very special conformal field theories in type IIB supergravity by Yu Nakayama

“…After constructing solutions in effective five dimensional Einstein gravity coupled with massive two-form fields, we uplift them to the ten dimensional type IIB supergravity, via a consistent truncation ansatz, to derive new analytical solutions in string theory. From the Kaluza–Klein ansatz in terms of the internal Sasaki–Einstein space, we obtain their field theory interpretation with concrete realizations in a large class of holographic N=1 supersymmetric conformal field theories. …”

Closed strings and moduli in AdS3/CFT2 by Olof Ohlsson Sax, Bogdan Stefański

“…Abstract String theory on AdS3 × S3 × T4 has 20 moduli. We investigate how the perturbative closed string spectrum changes as we move around this moduli space in both the RR and NSNS flux backgrounds. …”

Topological constraints in the LARGE-volume scenario by Daniel Junghans

“…Abstract We elaborate on recent results regarding the self-consistency of de Sitter vacua in the LARGE-volume scenario of type IIB string theory. In particular, we analyze to what extent the control over warping, curvature and g s corrections depends on the topology and the orientifold/brane data of a compactification. …”

On unitarity of the hypergeometric amplitude by Gareth Mansfield, Marcus Spradlin

“…Abstract The hypergeometric amplitude is a one-parameter deformation of the Veneziano amplitude for four-point tachyon scattering in bosonic string theory that is consistent with S-matrix bootstrap constraints. …”

Instanton corrections for m and Ω by Micha Moskovic, Ahmad Zein Assi

“…In this paper, we study instanton corrections in the N=2⋆ gauge theory by using its description in string theory as a freely-acting orbifold. The latter is used to compute, using the worldsheet, the deformation of the Yang–Mills action. …”

Branes and 2d N $$ \mathcal{N} $$ = (2, 2) gauge theories with orthogonal and symplectic groups by Oren Bergman, Eran Avraham

“…Abstract We construct two-dimensional N $$ \mathcal{N} $$ = (2, 2) supersymmetric gauge theories with orthogonal and symplectic groups using branes and orientifold planes in Type IIA string theory. A number of puzzles regarding the construction, including the effect of exchanging NS5-branes on an orientifold 2-plane, are resolved by lifting the configurations to M theory. …”

Selection rules for the S-Matrix bootstrap by Anjishnu Bose, Aninda Sinha, Shaswat S Tiwari

“…The Lovelace-Shapiro model, which was a precursor to modern string theory, is given by a straight line in the Adler zeros' plane and, quite remarkably, we find that this line intersects the space of allowed S-matrices near both these regions.…”

Non-invertible flavor symmetries in magnetized extra dimensions by Tatsuo Kobayashi, Hajime Otsuka

“…Abstract We discuss non-invertible symmetries in toroidal compactifications of higher dimensional Yang-Mills theory with magnetic fluxes, which can be regarded as an effective action of type IIB string theory with magnetized D-branes. Specifically, we derive fusion rules of discrete isometry operators, which are invariant under the ℤ N orbifold twist. …”
