Summary: In this study, we investigate the BPS submodels of the higher dimensional Skyrme model and their properties. Two possible BPS submodels, the BPS Skyrme model and the scale-invariant model, are found. The first submodel supports BPS Skyrmions with B >= 1, while the second submodel only has B = 1 BPS Skyrmion. The scale-invariant model exhibits a stronger self-duality condition compared to the BPS Skyrme model.

Summary: This study determines the higher symmetries of 5D SCFTs engineered from M-theory on a C3/r background and resolves the extraction of data when the resulting singularity is nontoric or not isolated. The BPS states of the theory are encoded in a 1D quiver quantum mechanics gauge theory and can also be extracted by computing the defect group associated with the orbifold singularity. The abelianization of r detects a 2-group structure when the geometry captures the global 0-form symmetry accurately.

Summary: In this paper, we studied the entanglement content of zero-density excited states in complex free quantum field theories, focusing on the symmetry resolved entanglement entropy. We showed that the ratio of Fourier-transforms of the symmetry resolved entanglement entropies takes a simple and universal form for these states. We also extended our results to excited states of interacting theories and developed a higher dimensional generalisation of the branch point twist field picture.

Summary: The study explores a class of unified models based on the gauge group SO(10) which generate a pair of light Higgs doublets needed for electroweak symmetry breaking. The inclusion of corrections to GUT scale Yukawa couplings allows for consistency of top, bottom, and tau masses with experiment for low tan beta values. The sparticle spectrum for a set of benchmarks shows satisfaction of relic density through compressed spectrum and coannihilation, with the possibility of discovery at both HL-LHC and HE-LHC.

Summary: This article investigates the higher-spin gravity in (A)dS4 space, which is defined as the holographic dual of a free O(N) or Sp(N) vector model. The theory is considered non-local at distances greater than the (A)dS radius due to a mismatch in the massless exchange terms. However, the study shows that in the Euclidean OPE limit, there are no massless exchange-type non-localities for any spin, suggesting that the higher-spin theory is local in spacetimes with Euclidean boundary signature. This implies locality in de Sitter space for Lorentzian bulk.

Summary: Toy models for the 5-D analog of the kinetic mixing/vector portal scenario were investigated, with dark matter and the dark Higgs now both localized to the 'dark' brane while only the dark photon remains a 5-D field. The phenomenology of this setup was explored and compared to previous, more complex models in both flat and warped extra dimensions.

Summary: The research reveals that in the holographic SU(2) p-wave superconductor model with Weyl corrections, the conductivity in the superconducting phase exhibits obvious anisotropic behaviors. In the superconducting phase, a behavior similar to a Drude peak emerges in the real part of the conductivity, regardless of the behaviors in the normal state.

Summary: We study minimal type-A higher-spin gravity in four dimensions, proposing new diagrammatic rules that involve Fronsdal fields and Didenko-Vasiliev particles. These rules can reproduce all n-point functions of the theory's holographic dual, the free O(N) vector model.

Summary: The YM theory has been generalized to 2YM and 3YM theories, and similarly, the BFYM theory has been generalized to 2BFYM and 3BFYM theories. It is shown that these higher BFYM theories can provide formulations for the corresponding higher form YM theories. Additionally, the gauge symmetries of these higher BFYM theories are also studied.

Summary: This paper studies Chern-Simons theories at large N with bosonic or fermionic matter in the fundamental representation. It classifies the conformal line operators along smooth paths and determines the spectrum of conformal dimensions and transverse spins of their boundary operators. The paper demonstrates that these line operators satisfy first-order chiral evolution equations and argues that this equation, along with the spectrum of boundary operators, uniquely determines the expectation values of these operators. The paper further shows that the line operators in the theories of bosons and fermions satisfy the same evolution equation and have the same spectrum of boundary operators.

Summary: This paper presents a method to address the limitations of charged black holes in (2 + 1)-dimensional anti-de Sitter space-time, by extending the parameter space of the BTZ geometry and properly identifying integration constants. The result is a well-defined internal energy, consistent with the Area Law, corresponding to a van der Waals gas.

Summary: This study proves a theorem in 3-dimensional topological field theory regarding the existence of nonzero boundary theory, and characterizes fusion categories based on duality, relying on the cobordism hypothesis with singularities. The main theorem applies to 3-dimensional quantum systems in physics, providing insight into the obstruction to the existence of a boundary theory. Appendices on bordism multicategories, 2-dualizable categories, and internal duals may be of independent interest.

Summary: Recent research on constructing a double copy of massive gauge fields has shown that the generic double copy is unphysical, but a new direction has been explored in three-dimensional spacetimes to obtain a sensible double copy of massive gauge fields. By requiring scattering amplitudes to satisfy a specific BCJ relation to avoid spurious poles at 5-points, it has been demonstrated that the amplitudes of Topologically Massive Yang-Mills satisfy this relation and that their double copy is Topologically Massive Gravity at three, four, and five-points.

Summary: Recently, there has been a revived interest in using large extra dimensions to address the dark energy problem. It has been argued that this may require a departure from Effective Field Theory (EFT) reasoning. By calculating Casimir energies in extra dimensions, the researchers show that the tower spacing scale is always an upper bound on the UV scale for the lower-energy effective theory within the domain of validity for EFTs. These towers of states have an important role in the cosmological constant problem, but there are difficulties in exploiting them.

Summary: This paper investigates the detection capability of the upcoming radio telescope Square Kilometre Array (SKA) for dark matter particles in a broad mass range from MeV to TeV, considering both annihilation and decay scenarios. By systematically studying the impacts on the DM-induced signal computation from magnetic field strengths and particle diffusion coefficients, the study compares the detection potential of different sources.

Summary: The supersymmetric model is an attractive extension of the Standard Model, and researchers propose using the Next-to-Minimal Supersymmetric Standard Model (NMSSM) to explain recent experimental anomalies. They find that a 60 GeV bino-like neutralino can successfully account for the observed excesses.

Summary: The recent measurement of the W-boson mass at Fermilab suggests the presence of new multiplets beyond the standard model. The introduction of an additional scalar doublet can naturally handle the new W-boson mass and the lightest scalar in the doublet can play the role of dark matter.

Summary: Two experiments from the Fermilab reported anomalies for muon g-2 and W-boson mass that may indicate new physics at the low energy scale. This study examines the possibility of a common origin of these anomalies in the Next-to-Minimal Supersymmetric Standard Model. Results show that lighter electroweakinos and sleptons can contribute to muon g-2 and W-boson mass, while the corresponding neutralino dark matter mass is in the 180-280 GeV range.
