Summary: In this study, we explore various conjectural dual descriptions of a stack of M2-branes in M-theory and propose several new dualities of the M2-brane SCFTs by analyzing flavored supersymmetric indices. The mappings of local operators, Coulomb, Higgs, and mixed branch operators as well as global symmetries under the dualities are obtained from the precise matching of the indices. We also find closed form expressions and more useful expressions for certain indices, which are significant for further research.

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: We address the computation problem of the Higgs branch H of linear quivers with 8 supercharges and with both unitary and special unitary gauge nodes. The solution involves the use of magnetic quivers to describe components of H as 3d N = 4 Coulomb branches, obtained through studying the brane web of an auxiliary 5d theory.

Summary: We derive a Lagrangian for a lightlike dimensional reduction of the nonabelian M5 brane theory in six dimension, assuming the six-manifold possesses at least one conformal Killing spinor and two commuting lightlike Killing vector fields. The reduction is performed along one of these lightlike directions.

Summary: The passage discusses how to remove the anomaly in supersymmetry in the presence of an R-symmetry anomaly and enlarging the corresponding current multiplet. It also explores the additional effects on Ward identities for other existing anomalies when the supersymmetry anomaly is removed. Finally, it validates the modified consistency conditions through explicit computation using Pauli-Villars regulators.

Summary: The study investigates circle compactifications of 6d superconformal field theories that lead to 5d rank 1 and rank 2 Kaluza-Klein theories. By including explicit dependence on bare gauge couplings and mass parameters, an accurate parametrisation of the prepotential including all parameters of the field theory is achieved. The resulting geometries exhibit a fibre-base duality, relating their six-dimensional origin to the purely five-dimensional quantum field theory interpretation.

Summary: We analyze the 6d (1, 0) SCFTs known as massive E-string theories in massive Type IIA with 8 - n(0) < 8 D8-branes close to an O8(-) (or O8* if n(0) = 8, 9), extending the analysis from [9]. The classification of the massive E1+(8-n0)-strings for different choices of n(0) is done using constrained E-8 Kac labels, which also reveal the flavor subalgebra of E1+(8-n0) for each SCFT. Hierarchies of Higgs branch RG flows are constructed for two types: flows between massive theories defined by the same n(0) but different labels, and flows between massive theories with different n(0), triggered by T-brane vev's for the right SU factor of the SCFT global symmetry.

Summary: The research reveals that the type-B conformal anomalies of Coulomb-branch operators in 4D N = 2 SCFTs always match on the Higgs branch, but there are anomalies that do not match when the IR Coulomb-branch chiral ring is not empty.

Summary: We explore the Higgs branch of 5d fixed points engineered using brane webs with an O7(+)-plane, proposing rules to extract magnetic quivers and calculating the Coulomb branch Hilbert series of these quivers. In some cases, alternative magnetic quivers can be obtained using ordinary brane webs or brane webs with an O5-plane, with a matching Hilbert series found.

Summary: This paper investigates the generation process of 5d SCFTs from 6d SCFTs, including the decoupling of hypermultiplet matter, RG-flow, and the construction of decoupling trees. By using the approach of generalized toric polygons, magnetic quivers and Hasse diagrams of 5d SCFTs are systematically derived, and the Higgs branches of various 5d KK-theories and their descendants are computed.

Summary: This paper studies the universal behaviors of a CFT in the presence of defects, proving that the defect a-anomaly must decrease under unitary defect RG flows and deriving the relation between the defect a- and c-anomalies and the U(1)(R) symmetry anomalies. The methods are illustrated with examples and the potential collider bounds on defect anomalies are discussed.

Summary: This article investigates the intersection between N M5-branes and the orbifold DOUBLE-STRUCK CAPITAL C-2/Gamma(ADE) and an E-8 wall, resulting in the discovery of 6d (1, 0) SCFTs called ADE-type orbi-instantons. The research reveals that these SCFTs are connected by Higgs branch RG flows, reducing the flavor symmetry of the UV fixed point. The authors determine the complete hierarchy of these RG flows for type A and provide a detailed diagram representation.

Summary: This study investigates new types of anomalies in conformal field theories with surface defects. By explicitly deriving and analyzing the scalar theory under defect RG flow, the b-theorem and a universal relation between the b-anomaly and U(1)(r) symmetry's 't Hooft anomaly are confirmed. Additionally, the b-extremization principle is established as a powerful tool for extracting the b-anomaly of strongly coupled surface defects.

Summary: In this work, the partition function for 6d N=1 SO(2N) gauge theories compactified on a circle with Z(2) outer automorphism twist is computed using 5-brane webs with two O5-planes and topological vertex. The results for representative examples of 6d SO(8) and SU(3) gauge theories with Z(2) twist are shown to agree with elliptic genus computations.

Summary: This study presents a detailed realization of the quantum field theory ensembles in D < 4 spacetime dimensions, allowing for a random averaging of coupling constants. The resulting volume, when each member of the ensemble is a conformal field theory with a standard semiclassical holographic dual, can be interpreted as an asymptotically anti-de Sitter space geometry with a distribution of boundary components joined by wormhole configurations. This construction provides a UV completion of the proposal for a high-dimensional Hilbert space for baby universes, while remaining consistent with the proposed swampland constraints.

Summary: This study reveals a finite-order mixed 't Hooft anomaly in five-dimensional non-abelian gauge theories, as well as an obstruction to coupling the U(1) global symmetry with a classical background gauge field associated with a one-form center symmetry. A similar obstruction is found to occur in gauge theories with fundamental matter. Furthermore, the general dynamical properties of the candidate phases implied by the anomaly are explored.

Summary: The study focuses on the correlation functions of Coulomb branch operators in four-dimensional N = 2 Superconformal Field Theories, particularly on rank-one theories. It is shown that the large charge limit of extremal correlators can be captured by a dual description of a chiral random matrix model of the Wishart-Laguerre type. This provides an analytic understanding of physics in specific excited states.

Summary: In this study, infinite families of non-supersymmetric AdS(6) solutions in Type IIB string theory are discussed, which are siblings of supersymmetric solutions connected by RG flows. The stability of non-supersymmetric solutions is studied, with perturbative and non-perturbative decay channels identified, and mechanisms for decay of solutions based on brane web considerations are proposed. Additionally, scale separation is excluded by constructing universal spin 2 modes with masses comparable to the mass-scale of the cosmological constant.

Summary: This paper focuses on 1-form symmetries of weakly coupled 6d supersymmetric gauge theories. The study shows that Dirac quantization imposes restrictions on consistent 1-form backgrounds and provides explicit criteria to determine whether the discrete 1-form symmetries are realized. The research is implemented in concrete examples and verified by finding a non-trivial fractional contribution related to the breaking of global 1-form symmetry.

Summary: We investigate the 2-group symmetries in 6d superconformal field theories, which arise from the mixing between the discrete 1-form symmetry and continuous flavor symmetry group. By applying the approach that is applicable more generally, we classify all 6d superconformal field theories with such 2-group symmetries and discuss the dimension-independent aspects of the analysis. We also provide a mathematical code for computing 2-group symmetries once the dimension specific input is provided.

Summary: The article discusses the existence and properties of 2-group symmetries in 5-dimensional superconformal field theories. The authors discover 2-group symmetries in 5-dimensional N=1 abelian gauge theories and determine the global forms of 0-form flavor symmetry groups in 5-dimensional SCFTs. The analysis also includes the study of 2-group symmetries in 5-dimensional N=1 non-abelian gauge theories and their relation to mixed 't Hooft anomalies between 1-form and 0-form symmetries.

Summary: We determine the d + 1 dimensional topological field theory, which encodes the higher-form symmetries and their 't Hooft anomalies for d-dimensional QFTs obtained by compactifying M-theory on a non-compact space X. The resulting theory, which we call the Symmetry TFT, or SymTFT for short, is derived by reducing the topological sector of 11d supergravity on the boundary 8X of the space X.

Summary: We propose a systematic approach to deriving symmetry generators in holography. We focus on noninvertible symmetries, which have emerged as a new type of symmetry in higher-dimensional quantum field theories. We provide an example in the holographic confinement setup, where the fusion of noninvertible symmetries arises from the Myers effect on D-branes.

Summary: This study focuses on confinement in 4d N = 1 SU(N) Super-Yang Mills theory, with an emphasis on the 1-form symmetry and its relation to chiral symmetry breaking. By examining the topological couplings in the 5d truncation of the Klebanov-Strassler solution, the determination of the 1-form symmetry and its 't Hooft anomalies is identified. The research also reveals an infrared 4d topological field theory that realizes chiral symmetry breaking and matches the mixed anomaly, shedding light on the connection between different symmetries in the theory.
