Summary: The study explores teleparallel gravity from a dynamical systems perspective, introducing a nonconstant degree of freedom to improve existing autonomous system models for a new dynamical analysis. By studying hyperbolic critical points, a possible solution to the H-0 tension in a cosmologically viable f(T,B) mixed power law model is suggested.

Summary: In this paper, we revisit the little string theories (LSTs) governing the dynamics of instantonic heterotic E-8 x E-8 five-branes probing ALE singularities. Our approach is based on 6d conformal matter and we determine these theories as generalized 6d quivers. The matching of the R-symmetry two-group structure constant is a stringent constraint for T-dualities and is used as a consistency check for the proposed realization of the 6d LSTs.

Summary: The study combines SU(5) Grand Unified Theories with A(4) modular symmetry, resulting in seven types of SU(5) models with A(4) modular symmetry. 53 benchmark models are presented with the fewest free parameters, and predictions for quark and lepton masses and mixing parameters are optimized to match experimental data. The best fit predictions for leptonic CP violating phase, lightest neutrino mass, and neutrinoless double beta decay parameter cover a wide range but cluster around specific regions, allowing future neutrino experiments to differentiate between model types.

Summary: We provide a general description of gauge symmetry breaking in 4D F-theory models using vertical and remainder fluxes. These fluxes can break a larger geometric gauge group to a smaller group and induce chiral matter. Specifically, we focus on the realization of the Standard Model gauge group and chiral matter spectrum through the breaking of rigid exceptional gauge groups E-7, E-6 in the F-theory landscape.

Summary: In this study, we compute the flux-induced F-term potential in 4d F-theory compactifications at large complex structure. We identify two families of vacua where complex structure fields are fixed and flux contributions are bounded. Our analysis provides explicit general expressions for the potential and explores the set of flux vacua for an arbitrary number of fields, linking our findings to previous results in the literature.

Summary: In this study, celestial amplitudes in (super) Yang-Mills theory are investigated using a parametrization of spinor helicity variables that allows for an unfixed overall phase. A new Mellin transform naturally yields the spin constraint h - (h) over bar = J for celestial conformal primaries, and the conformal transformation of celestial amplitudes is derived. The approach is applied to N = 4 super Yang-Mills, demonstrating the formulation of chiral celestial superamplitudes and the representation of generators of the four-dimensional superconformal algebra on the celestial sphere, which annihilate all tree-level celestial superamplitudes.

Summary: The study focuses on six dimensional supergravity theories with superconformal sectors and investigates the fate of the discrete 2-form global symmetries of the SCFT sectors. It is found that when the charge lattice of the SCFT sectors is non-primitively embedded into the charge lattice of the supergravity theory, a subgroup of these 2-form symmetries remains unbroken and must be gauged. This subgroup is determined by the embedding of the charge lattices, and examples as well as general observations are presented.

Summary: In this paper, we investigate various aspects of ZN rank-2 gauge theory in (2 + 1)-dimensional spacetime. We demonstrate that U (1) rank-2 gauge theory can arise from U (1) x U (1) rank-1 gauge theory after condensing the gauge charges in a specific way. The ground states of R2TC are constructed as two copies of the ground states of Kitaev's toric code that are sewn together according to the condensation scheme.

Summary: This article argues for the quantum-gravitational inconsistency of certain 6D N = (1, 0) supergravity theories and explains why the majority of these theories are not compatible with quantum gravity constraints using flavor symmetries. It also discusses how the automatic enhancement to a larger gauge sector remedies this inconsistency.

Summary: The solutions for the field equations of f(R) gravity in static cylindrically symmetric space-time were investigated. Unknown values of the equations of state parameter were determined through the analysis of constraints obtained by using the Noether symmetry method. Several new exact solutions for cases of General Relativity in static cylindrically symmetrical space-time for the non-dust matter were discovered.

Summary: This paper refines and establishes a set of old conjectures about symmetries in quantum gravity using the AdS/CFT correspondence. It shows the absence of bulk global symmetries in AdS/CFT and discusses how long-range bulk gauge symmetries lead to global boundary symmetries. The results are extended to higher-form symmetries and the weak gravity conjecture is applied to more general gauge groups.

Summary: This paper investigates the geometry of compact stellar objects using the Noether symmetry strategy in the framework of curvature-matter coupled gravity. The study finds that compact objects in this theory depend on conserved quantities and model parameters, with obtained solutions being compatible with astrophysical data. The results demonstrate the viability of this approach in analyzing the properties of compact objects.

Summary: We study the global anomalies of discrete gauge symmetries in six-dimensional supergravities and how they are realized in F-theory. We construct a discrete Green-Schwarz mechanism that depends on a coupling constant choice and a certain quadratic refinement in differential cohomology. By engineering theories with G = Z(3) gauge symmetry and no tensor multiplets, we find a specific choice of the quadratic refinement in F-theory. This leads to new Swampland constraints on the discrete charge spectra of 6d supergravities.

Summary: We discuss the phenomenology of no-scale supergravity, a theory that arises naturally from string theory and proposes zero scalar mass at a high energy scale. We focus on the recently updated muon g-2 measurement, dark matter, and the correct Higgs boson mass. We find that while no-scale SUGRA can satisfy the dark matter and Higgs boson mass requirements, the muon g-2 measurement may only be accommodated in certain regions of parameter space.

Summary: In this study, we investigate the leptogenesis phenomenon in three different realizations of the type Ib seesaw mechanism. It is found that the minimal type Ib seesaw model cannot produce the correct baryon asymmetry, while the extended type Ib seesaw model can explain the imbalance of matter and antimatter through resonant leptogenesis. Furthermore, the inclusion of dark matter is possible, and the masses of the Dirac right-handed neutrinos can be within the range accessible to future experiments.

Summary: The study focuses on the extended 2Higgs doublet model where the Standard Model Yukawa interactions are forbidden due to a global U(1)' symmetry. By considering various nonstandard contributions to the electron and muon anomalous magnetic moments within the model, it is shown that nonstandard contributions are possible within the experimental constraints. Benchmark points for both muon and electron anomalies are presented, along with numerical scans indicating the mass regions of the Higgs scalars in this scenario.

Summary: This paper presents a minimal type Ib seesaw model and proposes an extension introducing dark matter into the model, exploring the parameter space for dark matter production. The connection between dark matter production and laboratory experiments is discussed, especially in relation to the mixing between standard model neutrinos and heavy neutrinos. Parameters related to dark matter production are constrained by experimental results and can be tested further in future experiments such as SHiP.

Summary: In this paper, we discuss the dynamics of field configurations in the Proca theory of the real massive vector field, specifically focusing on a certain class of electric (magnetic) dipole-charged states. We construct these states to ensure that the long-distance structure of the mean electromagnetic field is initially set by the formula describing the electromagnetic field of the electric (magnetic) dipole. We analyze the evolution of this mean electromagnetic field over time and observe the phenomena of harmonic oscillations of the electric (magnetic) dipole moment far from the center of the initial field configuration, as well as the emergence of a spherical shock wave propagating at the speed of light near the center. Additionally, we discover a unique axisymmetric mean electric field configuration accompanying the mean magnetic field in magnetic dipole-charged states.

Summary: The time-dependence of AdS black hole interior geometries poses challenges to holographic duality and the traversability of wormholes. Quantum circuit complexity of strongly coupled matter can address the first challenge. Data from a phenomenological model show an upper bound on the complexity growth rate, which becomes stricter with the addition of angular momentum. The slowing of black hole interior dynamics at high specific angular momentum also occurs.

Summary: This article investigates the superconformal index Z of the 6d (2,0) theory on S5 x S1 and describes it using the quantum M2 brane theory in the large N limit. By studying M2 branes in a twisted product of thermal AdS7 and S4, the leading non-perturbative term at large N is shown to be reproduced by the 1-loop partition function of an instanton M2 brane wrapped on S1 x S2 with S2 c S4. Similarly, the partition function of a defect M2 brane wrapped on thermal AdS3 c AdS7 reproduces the BPS Wilson loop expectation value in the (2,0) theory. The article also comments on the analogy of these results with similar computations in the quantum M2 brane partition function in AdS4 x S7/DOUBLE-STRUCK CAPITAL Zk, which reproduced the corresponding localization expressions in the ABJM 3d gauge theory.

Summary: This paper explores the nature of spacetime in quantum gravity based on a new version of the holographic principle that establishes a connection between string theory and polymer holonomy structures. The research findings suggest that, for this relationship to hold, spacetime must be perceived as emerging from a fundamental structure with degrees of freedom corresponding to quantum correlations only.
