Summary: This work continues the study of one-loop partition function for higher derivative conformal higher spin fields in six dimensions and its holographic counterpart in seven dimensions. By considering specific boundary conditions and heat kernel coefficients, the authors were able to match UV and IR divergences and obtain independent anomaly coefficients. Further investigation into non Ricci-flat Einstein boundaries revealed a discrepancy in computations for spins higher than two.

Summary: The study analyzes the topological mass terms of BF type in supersymmetric M-theory compactifications to AdS(5) and discusses the dual field theories with distinct global discrete symmetries resulting from different choices of boundary conditions for the BF terms. It provides a detailed discussion on the 't Hooft anomalies for 4d N = 1 SCFTs arising from M5-branes wrapped on a Riemann surface without punctures, including theories from M5-branes at a DOUBLE-STRUCK CAPITAL Z(2) orbifold singularity. The anomaly polynomial computation through inflow reveals background fields for discrete global 0-, 1-, and 2-form symmetries, continuous 0-form symmetries, and axionic background fields properly interpreted in the context of anomalies in the space of coupling constants.

Summary: This paper explores the implications of an interacting non-metric (4, 0) supergravity theory in 6d, which can be truncated to non-metric (1, 0) supergravity theory coupled to various tensor multiplets in 5d. This suggests that there are uplifts of unified non-metric (1, 0) tensor-Einstein supergravity theories in d = 6 corresponding to specific magical supergravity theories in d = 5. The global symmetry groups of these theories are non-compact and the scalar manifolds exhibit varying properties across different unified theories.

Summary: This study introduces a method of describing interface fusion using fusion functors, which simplifies the computation process. In the SU(3)/U(2) Kazama-Suzuki model, fusion functors for a set of elementary topological defects were found, from which all rational B-type topological defects can be generated.

Summary: The study focuses on four-dimensional N = 2 superconformal field theories describing D3-branes probing the newly constructed N = 2 S-folds in F-theory. An infinite class of superconformal field theories related to S-fold theories via partial Higgsing is introduced, and various properties of both the S-fold models and this new class of theories are determined using field-theoretical techniques.

Summary: This article focuses on the construction of integrable lambda-deformed WZW models based on non-semisimple groups. Two different deformations of the Nappi-Witten plane wave with the same underlying symmetry algebra are constructed for the four-dimensional case. Additionally, a plane wave representing the deformation of a logarithmic CFT is constructed from the Penrose limit of the lambda deformation of the SU(2)/U(1) coset CFT.

Summary: This paper investigates the relation between the parity-odd and parity-even parts of correlation functions in theories with conserved or weakly broken higher spin symmetries, as well as their connection to the parity-even part computed from free theories. The well-known link between CFT correlation functions and de-Sitter amplitudes in one higher dimension implies a connection between parity-even and parity-odd amplitudes calculated using non-minimal interactions.

Summary: This paper constructs a supersymmetric Lagrangian for charged massive spin-2 and spin-3/2 fields in a constant electromagnetic background using the four-dimensional hybrid formalism for open superstring field theory. The hybrid formalism offers the advantage of manifest N = 1 d=4 spacetime supersymmetry, combining the spin-2 and spin-3/2 fields into a single superfield without the need for picture-changing or spin fields.

Summary: Using numerical bootstrap method, the critical exponents of minimal three-dimensional N = 1 Wess-Zumino models with cubic superpotential W similar to dijk Phi i Phi j Phi k are determined, where the tensor d(ijk) is taken to be the invariant tensor of specific permutation or Lie groups. The study also observes super-multiplet recombination, allowing for the determination of the scaling dimension of the super-field (Phi).

Summary: In this paper, constraints imposed by unitarity and crossing symmetry on conformal theories in large dimensions are analyzed. The results show that under certain conditions, the four-point function of identical scalar operators in a unitary conformal theory resembles that of the generalized free field theory. Additional assumptions about the spectrum of light operators can further extend the applicability of these results.

Summary: This study focuses on higher-point functions of scalar operators in CFTs, exploring OPE data involving multiple spinning operators. The lightcone blocks for five- and six-point functions in the snowflake channel are derived and used to analyze these correlators in the lightcone limit. The large spin expansion of OPE coefficients involving two or three spinning operators is determined. Results are verified by comparing with the block decomposition of higher-point functions in generalized free theory and in theories with a cubic coupling.

Summary: In this study, properties of four-point colour ordered scattering amplitudes in D = 6 fishnet CFT were investigated, revealing a simple relation to their D = 4 counterparts previously studied in literature. This relation allowed for a closed expression of the amplitudes to be obtained and their behavior at weak and strong coupling to be explored. Additionally, a generating function for on-shell D = 6 Box ladder diagrams with l rungs was derived as a byproduct of this investigation.

Summary: This work presents momentum space Ward identities related to broken higher spin symmetry as an alternate approach to compute correlators of spinning operators in interacting theories. The authors use higher spin equations to obtain parity even and parity odd contributions to correlators involving spinning and scalar operators in a general kinematic regime, and match their results with existing literature when available. The interesting fact that higher spin equations can be used away from the conformal fixed point is illustrated by considering mass deformed free boson theory and solving for two-point functions of spinning operators using higher spin equations.

Summary: We studied the p-dimensional conformal defect of a free Dirac fermion on a d-dimensional flat space and found important properties regarding boundary conditions. For a two-codimensional defect, a double trace deformation triggers a renormalization group flow from the Neumann boundary condition to the Dirichlet boundary condition, with the free energy at the UV fixed point always larger than that at the IR fixed point.

Summary: This paper investigates the stability issue of vacuum compactifications from a higher-dimensional perspective. It focuses on the stability of supersymmetric vacua, analyzes the nucleation of brane bubbles in type II AdS compactifications, adapts positive-energy theorems to M-theory and type II supergravity, and discusses the inclusion of localized sources. The paper also discusses the inability to stabilize skew-whiffed and Englert vacua at the lower-derivative level in M-theory.
