Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.
At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper demonstrates that Hellinger-distance based coherence in two-flavor neutrino oscillations exhibits a unique nonanalytic sensitivity to weak decoherence, making it a significantly more responsive probe of damping effects than traditional quantifiers like concurrence or transition probabilities.
This paper investigates the classical stability of topological non-Abelian strings arising from the symmetry breaking of in models with two Higgs fields, utilizing time-dependent perturbations to establish stability constraints for specific winding configurations and demonstrating that general mixed-winding strings are stable only in the semilocal limit of a large mixing angle.
This paper demonstrates that darkogenesis scenarios, where a dark-sector particle transports asymmetry over large distances before decaying into visible baryons, naturally resolve the problem of baryon inhomogeneity induced by supercooled phase transitions, thereby avoiding stringent constraints from Big Bang Nucleosynthesis.
This paper calculates T-even twist-3 quark transverse momentum dependent parton distributions using the quark target model to address the lack of direct phenomenological fits needed for understanding beam single spin asymmetries and the 3-D structure of the proton.
This study demonstrates that while both rope hadronization and hydrodynamic evolution can describe certain aspects of strangeness production in heavy-ion collisions, only the hydrodynamic approach successfully reproduces transverse dynamics, indicating that simultaneously constraining both strangeness yields and transverse flow is essential to distinguish between thermal and non-thermal mechanisms.
Using the JAM2 transport model with RQMDv mean-field dynamics, this study investigates event-by-event mean- fluctuations in Au+Au collisions at 3.0–19.6 GeV, finding that while the model qualitatively reproduces spectra and scaled fluctuations at higher energies, it exhibits stronger centrality dependence than data at lower energies and reveals species-dependent correlator behaviors that evolve similarly to elliptic flow without establishing a common microscopic origin.
This paper proposes an environment-dependent mass splitting mechanism driven by an ultralight scalar coupled to electrons to suppress solar capture constraints on the inelastic-doublet interpretation of the LZ experiment's 248 keV event, demonstrating its phenomenological viability despite severe fine-tuning requirements.
Motivated by a high-energy recoil candidate from LUX-ZEPLIN, this paper demonstrates that while matched fermionic and scalar dark matter models yield similar direct-detection signals and late-time solar annihilation rates, their distinct excited-state lifetimes and gauge-boson branching fractions create unique neutrino spectra that allow solar evolution to serve as a complementary probe for distinguishing these otherwise degenerate particle physics models.
This paper compares the critical regions around the chiral critical end point in two-flavor and 2+1-flavor Polyakov-quark-meson models, analyzing how different treatments of vacuum fluctuations (on-shell renormalization versus curvature-mass parametrization) and flavor content influence the extent and location of enhanced quark number susceptibility.
This paper proposes a novel search strategy for the scotogenic model at the High-Luminosity LHC that targets a unique "nested" signature of a disappearing track followed by a displaced vertex, leveraging time-of-flight and spatial correlations to achieve background-free discovery of long-lived particles that simultaneously explain neutrino masses.
