Dipole-dipole scattering at high energy in the Pomeron field theory with Braun Hamiltonian and beyond

This paper demonstrates that within the Pomeron field theory with the Braun Hamiltonian, the dipole-dipole scattering matrix in the saturation region scales as the fourth power of the Balitsky-Kovchegov amplitude ( ${\cal S}^d_d \propto {\cal S}_{BK}^4$ ), a result that contradicts predictions from rare fluctuation approaches and large Pomeron loop summations, while arguing that the latter can be trusted up to energies of $Y \leq 1/\alpha_s^4$ .

IR Black Hole Instabilities Trigger Species-Scale Particle Production

This paper proposes a novel UV-IR mechanism in quantum gravity where black holes reaching a critical temperature associated with a light tower of states undergo a phase transition that produces species-scale particles, a process shown to be distinct from and dominant over standard Hawking radiation across various black hole configurations.

Spectral Functions of $J/\psi$ Meson in Rotating Thermal Background from Holography

Using a soft-wall holographic model, this paper investigates the spectral functions of the $J/\psi$ meson in a rotating thermal background, revealing that global rotation induces energy shifts proportional to angular momentum for parallel momentum while causing significant triplet splittings and deviations from simple shifts for perpendicular momentum.

Aspects of the quantization of non-linear electrodynamics in an uniform magnetic background

This paper proposes canonical and path integral quantization methods for non-linear electrodynamics in a uniform magnetic background by linearizing the theory around the external field, and subsequently applies this framework to calculate ground state energy, analyze microcausality, derive Green functions, and compute the one-loop effective potential for the Modified Maxwell model.

A Simple Pendulum in Schwarzschild Spacetime

This paper determines the small-oscillation period of a simple pendulum in Schwarzschild spacetime by modeling the rope as a spatial geodesic, deriving a formula expressed via the Schwarzschild lapse function that recovers the classical Newtonian result in the weak-field limit while differing from previous studies that assumed a coordinate-length constraint.

Scalaron-driven Dark Matter during Warm Inflation via UV Freeze--in

This paper investigates the production of dark matter via the ultraviolet freeze-in mechanism within warm Higgs-Starobinsky inflation, demonstrating that non-renormalizable operators of mass dimensions 8 and 9 can successfully generate the observed relic abundance for MeV to GeV-scale dark matter masses near the transition from inflation to the radiation-dominated era due to efficient energy transfer from the scalaron.

Measurement of the Hubble constant with high-energy neutrinos

This paper presents the first observational realization of a new neutrino-based distance ladder method using high-energy astrophysical neutrinos from 12 Seyfert galaxies to measure the Hubble constant, yielding a result of $H_0 = 49^{+40}_{-30}\,\mathrm{km\,s^{-1}\,Mpc^{-1}}$ that is consistent with existing determinations while demonstrating a novel approach free from electromagnetic propagation systematics.

Misconceptions About the Physics of the QCD Trace Anomaly from Renormalization in a Reducible Basis

This paper argues that the recently introduced reducible-basis renormalization method has generated misconceptions regarding the QCD trace anomaly, thereby obscuring its established, regulator-independent, and scheme-free nature and leading to flawed interpretations of nucleon mass and internal forces.

Thermal Evolution and Hydrodynamic Filtering of Pseudoscalar Dark Matter

This paper investigates how hydrodynamic effects, specifically shock heating during the deflagration regime of a first-order phase transition in a complex singlet extension of the Standard Model, significantly enhance the abundance of pseudoscalar dark matter even when it has already frozen out prior to nucleation.

Impact of Higgs precision measurements at the LHC and FCC-ee on the spectrum of composite Higgs models

This paper investigates the minimal $\mathrm{SU}(4)\rightarrow\mathrm{Sp}(4)$ composite Higgs model by translating current and projected Higgs precision measurements from the LHC and FCC-ee into constraints on the vacuum alignment angle and the singlet pseudo-Nambu-Goldstone boson mass, demonstrating that future experiments will significantly tighten the lower bound on the singlet mass from approximately 440 GeV to over 2 TeV.
