Summary: Recently, a new method to construct minimal linear codes using vectorial Boolean functions is proposed. The necessary and sufficient condition for a generic class of linear codes from vectorial Boolean functions to be minimal is derived. Moreover, three infinite families of minimal linear codes violating the AB condition are obtained. The minimal linear codes obtained in this paper generally have higher dimensions compared to other known ones.

Summary: This study shows that the recent measurements of the anomalous magnetic moment of the muon and dark matter can be explained simultaneously within the minimal supersymmetric standard model, with the most interesting parameter space regions to be tested by the next generation of dark matter direct detection experiments.

Summary: In this article, we investigate the properties of a continuous map f on a dendrite X. We obtain conditions on the structure of X and the set M, such that f has an arc horseshoe and, therefore, a positive topological entropy. We show that this result is not valid for continuous maps with an empty set of periodic points or for continuous maps with a non-empty set of periodic points on finite graphs.

Summary: We investigate the flavour bounds on Z(2) Z(5) and Z(2) Z(9) flavour symmetries, which are minimal and non-minimal forms of the Z2 ZN flavour symmetry. These symmetries can explain the masses and mixing pattern of fermions, including neutrinos, in the standard model. We derive bounds on the flavon field of these symmetries using current quark and lepton flavour physics data and future sensitivities. The strongest bounds come from D-0 - (D) over bar (0) mixing for the Z(2) Z(5) symmetry.

Summary: The symmetric quantum Rabi model and the asymmetric quantum Rabi model exhibit different symmetry properties, but show similar characteristic degeneracies at certain parameter values. Recent research has identified an operator that commutes with the Hamiltonian of the asymmetric quantum Rabi model, possessing important algebraic properties.

Summary: By utilizing the gauge/string duality, researchers have been able to investigate the string breaking phenomenon in the three-quark system. The study revealed that the string breaking distance is not universal and varies according to the geometry of the quarks, with some geometries allowing for multiple breaking distances. The ratio of string breaking distance in the three-quark system to that in the quark-antiquark system was estimated to range from approximately 2/3 to 1.

Summary: Transitions from incoherent to coherent dynamical states can be observed in various real-world networks, and they can be explosive or continuous. The nature of the transition changes depending on the initial conditions, and the critical coupling strength for explosive synchronization also depends on the initial conditions.

Summary: The study demonstrates the potential of realizing warm inflation in a minimal extension of the Standard Model, which can address various shortcomings of the Standard Model. The use of symmetries within the model not only helps to protect the scalar potential against thermal corrections, but also provides a possible explanation for the existence of dark matter.

Summary: In the MSSM, the mass of the lightest neutral Higgs boson is determined by the supersymmetric parameters. In the m(h)MSSM, the precisely measured Higgs boson is used as input parameter instead of the trilinear coupling A(t). Expressions are derived to extract A(t) as a function of the light Higgs boson mass in a semi-analytical form. An algorithm is developed and implemented at two-loop precision, which can be extended to higher orders, to consistently perform this inversion. The result of the algorithm, implemented in the SuSpect spectrum calculator, is demonstrated on a parameter set compatible with LHC measurements.

Summary: Two recent papers reported the discovery of the new isotope Md-244, but the decay data presented in Pore et al. and Khuyagbaatar et al. are conflicting. Pore et al. report two isomeric states decaying by alpha emission, while Khuyagbaatar et al. report only a single transition. By comparing the data from different studies, it is concluded that the data presented in Pore et al. should be attributed to Md-245.

Summary: This paper examines the scenario in which the majority of dark matter is composed of particles produced by the evaporation of primordial 2-2-holes, with the remnant contribution being secondary. The products with sufficiently light mass may contribute to the number of relativistic degrees of freedom in the early universe. Additionally, 2-2-hole evaporation can produce particles responsible for baryon asymmetry.

Summary: It is shown that uncertainty in the causal structure of field theory is inevitable when quantum gravity is involved, including the ill-definition of lightcones. This uncertainty is small in the effective field theory regime but grows with energy, representing an unknown factor for a generic UV completion. The mechanisms uncovered in effective field theory and quadratic gravity could be common features of quantum gravity.

Summary: This study investigates the Standard Model with gauged Z(N=2,3,6)((1)) subgroups of its Z(6)((1)) 1-form global symmetry, showing the existence of self-dual instantons of fractional topological charge on a finite T-3. However, the contribution of these instantons is suppressed by the small hypercharge coupling unless the torus size is sub-Planckian or additional matter is added above the weak scale. These results are discussed in relation to cosmological constraints on torus size.

Summary: With the progress in observing astrophysical black holes, it is crucial to understand the physics of strongly gravitating horizonless objects. This paper focuses on self-gravitating compact systems without event horizons, exploring their thermodynamic behavior without relying on field equations. The conventional first law of thermodynamics is retrieved, and connections to black hole thermodynamics are discussed.

Summary: It is demonstrated that quantum corrections from a massive particle lead to the generation of a nonlocal term in the gravitational effective action, similar to the cosmological constant but with a much larger fixed coefficient that cannot be fine-tuned. This interaction is effective at scales above the particle's mass, and poses challenges to its interpretation.

Summary: This paper discusses the contributions to the cosmological constant and how they vanish in perturbation theory, introducing a new interaction in path integral treatment to reduce the sensitivity of the cosmological constant to high-energy cutoffs. However, this does not solve the cosmological constant problem, and challenges some common motivations for supersymmetry and results of the asymptotic safety program.

Summary: In theories with higher time derivatives, the Hamiltonian analysis predicts an instability, but this instability can be avoided in some cases. The Hamiltonian treatment does not correspond to the way these theories are treated in quantum field theory.
