Using an improved Multi-Phase Transport model, this study demonstrates that the nuclear geometry and potential alpha clustering in O significantly influence anisotropic flows in O+O collisions at GeV, with the model successfully reproducing STAR data and establishing a baseline for future nuclear-structure investigations.
This paper presents a new local electron density map derived from parallax measurements of nearby pulsars, which suggests that many previously distant neutron stars are actually much closer and thus ideal candidates for future parallax campaigns to test fundamental physics, including dark matter heating mechanisms.
This paper derives and interprets the spatial density distributions of the axial-vector charge density for spin-1/2 systems using sharply localized wave packets in arbitrary Lorentz frames, while also examining the static approximation and its relation to Breit-frame distributions.
FeynGame 3.0 is a major software update that introduces QGRAF integration for visualizing Feynman graphs and implements various new features to facilitate the creation of publication-quality diagrams.
This paper presents a minimal Zee-Babu neutrino model utilizing non-holomorphic modular symmetry that successfully fits neutrino oscillation data under normal hierarchy near , predicts specific CP phases and neutrinoless double beta decay signatures, and addresses modulus stabilization within a non-supersymmetric framework.
This paper formulates an effective field theory for coupled dark energy and dark matter by integrating vector-tensor and non-relativistic fluid sectors, deriving linear perturbation equations and stability conditions, and demonstrating that energy-momentum transfers can reduce the effective gravitational coupling of dark matter at low redshifts.
This paper proposes using a single-arm interferometer with spatially separated squeezing operations to detect the interaction between photons and a scalar dark matter field, offering a novel method to reveal and constrain the parameters of such dark matter models.
This paper proposes a modified majoron model featuring both gauged and global symmetries that generates a network of cosmic strings capable of explaining the NANOGrav 15-year gravitational wave signal while simultaneously accounting for neutrino masses and satisfying cosmological constraints, albeit with the majoron's dark matter contribution remaining subdominant in the signal-favored parameter space.
This paper investigates monophoton signatures from scalar portal dark matter produced at neutrino facilities, demonstrating that distinct energy, angular, and spatial distributions allow experiments like DUNE ND to effectively separate these signals from neutrino backgrounds and place significantly improved constraints on dark matter parameter space.
This paper proposes that heavy decaying dark matter can serve as a novel probe for relic neutrino clustering by generating ultrahigh-energy neutrinos whose interaction with the cosmic neutrino background, when analyzed via transport equations, could reveal local overdensities of up to at future telescopes like IceCube-Gen2.
