This paper proposes a novel methodology to estimate the extragalactic photon flux generated by axions produced and subsequently decaying from Primordial Black Holes, suggesting that future detectors like e-ASTROGAM are well-positioned to observe this signal.
This paper investigates the confinement/deconfinement transition in pure Yang-Mills theories using the Curci-Ferrari model, demonstrating that predicted transition temperatures are robust against variations in renormalization scale and scheme, and align closely with lattice simulation results, thereby validating the model's effectiveness as an infrared description.
The paper proposes a novel nuclear interferometer utilizing the thorium-229 clock transition to detect ultra-light dark matter, offering enhanced sensitivity to variations in fundamental constants and the QCD sector that could complement and surpass existing terrestrial clock experiments.
This paper investigates the mass spectra and strong and radiative decay properties of high-lying $2D1F$ charmonium states around 4 GeV, incorporating unquenched effects to provide theoretical predictions that guide future experimental searches at facilities like BESIII, Belle II, LHCb, and STCF.
This paper employs the Lanczos algorithm to investigate Krylov complexity in the early universe as an open system across inflation, radiation, and matter domination epochs, revealing distinct dissipative behaviors, the similarity of complexity evolution across various inflationary potentials, and deriving new evolution equations for squeezing parameters via Meixner polynomials to demonstrate rapid decoherence-like effects.
This review examines the fundamental principles of thermal field theory in a background magnetic field, focusing on equilibrium systems to analyze bulk thermodynamic properties and real-time observables relevant to the thermo-magnetic QCD plasma in heavy-ion collisions.
This paper proposes an observable that distinguishes between quark and hadron phases in a finite-temperature quark-gluon plasma by linking the energy cost of static quark probes (via Polyakov loops) to the medium's capacity to screen them through meson or baryon formation.
This paper defends Large-Momentum Effective Theory (LaMET) against recent claims that it suffers from an unquantifiable inverse problem, arguing that physics-guided systematic extrapolation remains the most reliable method for estimating uncertainties in parton distribution calculations even when lattice data precision is suboptimal.
This paper proposes a novel mechanism called Magnetically Arrested Transmutation (MAT), wherein strong magnetic fields in compact stars halt the accretion of endoparasitic black holes formed by dark matter, thereby explaining the over-representation of magnetic white dwarfs and the unique presence of magnetars near the Galactic center.
This paper demonstrates that local over-densities, such as experimental cavities, can significantly suppress the amplitude and gradient of quadratically coupled ultra-light scalar dark matter, thereby hindering detection efforts and relaxing existing constraints on such models, while also proposing a differential force measurement between cavities of different internal structures as a potential detection method.
This paper presents a theoretical study using unitarized chiral interactions to calculate and correlation functions, demonstrating that the inclusion of strong scattering effects—particularly the subthreshold resonance for and the mildly repulsive force for —successfully reproduces ALICE experimental data and validates femtoscopy as a powerful tool for probing strangeness-related hadronic interactions.
This paper reviews how recent advancements in Large Momentum Effective Theory (LaMET), including improved renormalization schemes, higher-order matching kernels, and novel lattice operators, are enhancing the precision and reliability of first-principles lattice QCD calculations for proton parton distributions.
This paper employs QCD sum rules to systematically study pentaquark states with isospin , determining their mass spectra and proposing assignments for the observed candidates while identifying a lowest hidden-charm state just above the threshold.
This paper proposes a seeded axion-photon conversion scheme that utilizes a coherent seed electromagnetic field to constructively interfere with regenerated photons, thereby significantly enhancing the sensitivity of short-pulse light-shining-through-a-wall experiments where traditional resonant cavities are impractical.
Through -body simulations, this study critically assesses claims that dark matter spikes explain anomalous period decays in three low-mass X-ray binaries, ruling out previously proposed shallow profiles and establishing that significantly steeper density slopes () are required to account for the observed orbital evolution.
This paper provides a conceptual and practical introduction to Strong-Field Quantum Electrodynamics tailored for experimentalists, focusing on core ideas, terminology, and challenges relevant to experimental design and interpretation rather than offering a comprehensive theoretical review.
This paper analyzes hadronic final states at Future Circular Electron-Positron Collider (FCC-ee) energies using PYTHIA simulations to investigate event shapes and inclusive spectra, extract the strong coupling constant with NNLO accuracy, and assess systematic uncertainties and soft gluon dynamics for future QCD studies.
This paper proposes a model within the Dark Dimension scenario where a gauged B-L symmetry in the bulk naturally generates three right-handed neutrinos and a tower of sterile states, while Higgsing the symmetry at the electroweak scale yields a massive, weakly coupled gauge boson and theoretically explains the coincidence between neutrino masses and the Dark Energy scale.
This paper proposes a new mechanism linking the asymmetric dark matter mass scale to the proton mass by introducing an extended color group with a spontaneously broken symmetry that relates the QCD and dark gauge couplings, resulting in comparable confinement scales and a rich TeV-scale spectrum.
Using 22 years of INTEGRAL/SPI data to analyze 18 nearby pre-supernova stars, this study finds no evidence of axion-like particle-induced emission and establishes some of the strongest constraints to date on ALP-photon and ALP-electron couplings for masses up to $10^{-11}$ eV.
