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 develops a consistent field-based perturbation framework to analyze the impact of oscillating generalised axion-like quintessence fields on cosmic structure growth, demonstrating that the standard effective fluid description fails during this dynamical phase.
This paper presents a theoretical analysis of the decay using the chiral unitary approach, demonstrating that the inclusion of a dynamically generated resonance alongside other intermediate states successfully reproduces recent Belle experimental data and supports the interpretation of as a meson-baryon coupled-channel state.
This paper benchmarks three exclusive nuclear ground-state shell models implemented in the NEUT neutrino event generator against recent JSNS measurements of missing energy from a monoenergetic neutrino beam, finding that spectral function models outperform relativistic mean field models and that accounting for missing energy thresholds allows all tested nuclear models to be statistically accepted.
This paper demonstrates that operating the Short-Baseline Near Detector (SBND) at Fermilab in off-target or beam-dump configurations significantly suppresses neutrino-induced backgrounds, thereby substantially extending its sensitivity to probe various new physics scenarios such as light dark matter, axion-like particles, heavy neutral leptons, and meson-portal models.
This paper argues that while a complex New Physics coupling proposed to explain mild deviations in data conflicts with LHC high- constraints, other viable scenarios exist that are too subtle for integrated observables but may be detectable via -binned angular distributions in specific and decay modes.
This paper evaluates the LHC's potential to detect the scalar radial excitation in composite and twin Higgs models, establishing current mass bounds of 0.93–1.13 TeV from Run 2 data and projecting HL-LHC sensitivities up to 2.2 TeV, with the Higgs pair decay channel identified as the most promising discovery mode.
This paper demonstrates that relational observables in quantum gravity can be expressed as dressed operators, revealing that the algebraic structure of quasi-de Sitter space corresponds to a Type II von Neumann algebra due to isometry breaking, which fundamentally distinguishes it from the Type II algebra of de Sitter space.
This paper investigates the low-energy phenomenology of a 3+3 Type-I seesaw framework by performing a comprehensive Monte Carlo scan to constrain sterile neutrino parameters against oscillation data and multi-probe limits, revealing that while eV-scale sterile states induce significant spectral distortions, they face strong tension from charged-lepton flavor violation bounds and predict a neutrino mass sum within the reach of future cosmological surveys.
This paper investigates the sensitivity of current and future hadron-collider experiments to axion-like particles (ALPs) via associated diboson production, deriving four-dimensional constraints on their couplings to gluons, weak bosons, and photons, and highlighting the potential of the High-Luminosity LHC to probe the sub-GeV mass range.
This paper presents a novel deep convolutional neural network-enhanced Bayesian global analysis of relativistic heavy-ion collisions that significantly reduces computational costs to constrain QCD matter properties, revealing a temperature-dependent shear viscosity plateau and non-zero bulk viscosity while confirming that hydrodynamic freeze-out occurs at the expected applicability limit.
