This paper systematically analyzes ultralight dark matter effects on neutrino oscillations using T2K and NOA data, revealing that stochastic fluctuations in the low-mass regime significantly relax coupling constraints while failing to resolve the existing tension in the CP-violating phase between the two experiments.
The paper demonstrates that the standard low-energy effective field theory of quantum gravity predicts unobservably small vacuum fluctuations in interferometers, implying that any future detection of large gravitationally-induced length variations would signal a fundamental breakdown of this theory.
This paper revisits the production of axion-like particles coupled to electrons in supernovae by incorporating previously neglected processes and thermal corrections to derive analytical emissivity rates, ultimately updating astrophysical constraints from SN 1987A across various coupling regimes.
This paper proposes a novel low-scale leptogenesis mechanism enabled by a first-order electroweak phase transition, which keeps sphalerons active below the standard decoupling temperature to convert lepton asymmetry into baryon asymmetry even for right-handed neutrinos with masses as low as 35 GeV, offering potential detection signatures through stochastic gravitational waves and accelerator experiments.
This paper derives gravitational positivity bounds for the Higgs-portal scalar dark matter model, revealing that new physics must emerge below GeV for light dark matter without self-coupling, while heavy dark matter (– GeV) with specific couplings can satisfy grand unified theory scale constraints and be consistent with the observed relic abundance via the freeze-in mechanism.
This paper investigates normal mode analysis in relativistic massive transport by demonstrating how particle mass induces coupling between sound and heat channels, alters the branch cut structure responsible for Landau damping, and leads to non-monotonic dependencies in the critical wavenumbers for collective modes.
This paper calculates the binding energies of excited positronium states using the two-body Dirac equations of constraint, comparing nonperturbative and perturbative results while correcting identified literature errors and validating the model against alternative formulations.
This paper presents a systematic framework for deriving non-relativistic effective field theories from relativistic theories with generic, potentially non-analytic self-interactions, establishing an effective fluid description and extending the formalism to cosmological settings to analyze ultra-light dark matter models, boson stars, and dark matter halo cores.
This paper introduces a computationally efficient Bayesian framework for Parton Distribution Function (PDF) determination that utilizes low-dimensional linear models derived from neural network bases to provide robust uncertainty estimates and transparent control over model selection, as validated through synthetic data and closure tests.
This paper proposes that resonant cavities can enhance the decay rate of axion dark matter into two photons via the Purcell effect, offering a competitive and complementary search method that can be implemented using existing axion heterodyne detection schemes with minimal modification.
This paper demonstrates that chiral-odd dimeson generalized distribution amplitudes, which encode the spin-orbit correlation in spin-zero mesons, can be experimentally accessed in reactions through the interference between leading one-photon and two-photon exchange amplitudes, offering a direct path to probe this previously unmeasured sector of meson structure at facilities like BES III.
This paper refines the theory of axion double level crossings in multi-axion systems, demonstrating that these phenomena—characterized by a high-temperature crossing followed by a QCD-induced crossing—are common in axion models but are constrained by the number of axions () in both light and heavy scenarios, with significant implications for axion cosmology.
This paper proposes using linear Paul traps with single or multi-ion configurations to detect megahertz gravitational waves via graviton-photon conversion or relative-motion excitations, demonstrating that entangling vibrational qubits enhances signal probability by a factor of to surpass the standard quantum limit.
This paper investigates a parity-symmetric extension of the Standard Model that naturally explains small neutrino masses while allowing for substantial TeV-scale lepton number violation, demonstrating that a 10 TeV collider could probe boson masses up to 16 TeV through distinctive lepton number violating signals.
This paper utilizes finite-temperature QCD sum rules with updated quark masses and lattice-informed condensates to predict the thermal evolution of masses and decay constants for , , and mesons up to near-critical temperatures, revealing a suppression hierarchy consistent with binding energies and confirming the -- splitting observed by LHCb.
This paper investigates how diverse pre-nucleosynthesis cosmological histories, termed "weather," create distinct "seasons" in the momentum distribution of freeze-in dark matter, thereby determining its warmness and establishing crucial mass bounds based on the early universe's composition.
This paper investigates the minimal type II seesaw mechanism with two-zero neutrino mass textures, demonstrating how specific patterns of charged lepton flavor violation—particularly in tau decays—can be distinguished from other new physics scenarios and used to probe ultra-high flavor symmetry scales and doubly charged scalars at current and future experiments.
This paper utilizes the instanton liquid model enhanced by correlated instanton-anti-instanton pairs to derive and analyze the transverse distribution of the color Lorentz force acting on quarks in pions and nucleons, demonstrating that these force form factors are intimately related to gravitational and transversity form factors and yield results for nucleons consistent with recent lattice QCD calculations.
This paper proposes a machine-learning-based strategy that classifies neutrino interaction types prior to energy reconstruction to exploit intrinsic kinematic differences, thereby reducing modeling uncertainties and improving the accuracy and sensitivity of next-generation long-baseline oscillation experiments like DUNE by 10–20%.
This review paper examines hadron structure within the covariant Nambu-Jona-Lasinio model as a chiral effective theory of QCD, demonstrating its ability to replicate spontaneous chiral symmetry breaking and confinement while validating consistency with parton distribution functions and electromagnetic form factors against experimental data and future collider prospects.
