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 proposes a single-flavon Froggatt-Nielsen framework organized by a two-over-two lattice structure, where quark and charged-lepton mass hierarchies are reproduced as powers of a single parameter through the summation of three messenger chains that generate complex coefficients and CP violation.
This paper proposes that a minimal dark scalar with a mass of approximately 9.40 GeV, which shares high- fragmentation scaling with NRQCD color-octet production, can simultaneously explain the anomalous high- plateau in nuclear modification factors, the vanishing elliptic flow, and the quarkonium polarization puzzle in heavy-ion collisions while evading historical low- constraints.
This paper presents a comprehensive effective field theory pipeline that connects baryon number-violating new physics to low-energy hadronic observables by systematically matching Standard Model EFT operators up to dimension nine to Low-Energy EFT and chiral perturbation theory, thereby enabling a model-independent analysis that incorporates higher-dimensional operators and a broader class of ultraviolet completions than previously possible.
This paper introduces a self-supervised, transformer-based approach that generates oracle trajectories by scrambling and unscrambling mathematical expressions to achieve near-perfect symbolic simplification in high-energy physics tasks, significantly outperforming prior reinforcement learning and regression methods.
This paper proposes a unified framework where ultra-slow-roll inflation simultaneously generates primordial black hole dark matter, the baryon asymmetry via spontaneous baryogenesis, and a detectable stochastic gravitational wave background, establishing a predictive correlation between these phenomena that can be distinguished by future gravitational wave observatories like LISA, DECIGO, and the Einstein Telescope.
This paper demonstrates that perturbative reheating following inflation systematically suppresses the gravitational wave signals from cosmological phase transitions compared to standard radiation-dominated scenarios, while introducing characteristic spectral features that could serve as distinctive signatures of the modified expansion history.
This paper employs both machine learning techniques and an extended analytical mass formula to predict the mass spectra of fully-heavy baryons and exotic pentaquarks, offering complementary insights that align with existing experimental data and guide future searches for unobserved states.
The paper proposes "Unified Flavor," a framework where hierarchical Yukawa couplings and CP violation emerge from TeV-scale vectorlike fermion chains on a -lattice governed by a single flavon, successfully reproducing quark and lepton mass spectra while simultaneously addressing flavor constraints, strong CP, and offering testable predictions for future experiments.
This paper applies an effective field theory formalism to two-meson tau decays, concluding that future experiments with 5% precision on modes can test the maximum allowed CP rate asymmetry to either validate or refute the BaBar anomaly in decays.
This paper investigates energy-momentum tensor form factors and spatial spin density distributions in the nucleon using a quantized Skyrme model with vector mesons, demonstrating that while global nucleon properties remain invariant, the choice of pseudogauge (canonical versus Belinfante) significantly alters the local interpretation of spin and momentum densities.
