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 while next-generation neutrino observatories like Jinping could theoretically detect the intense neutrino burst from a stellar helium flash out to nearly 3 parsecs, the absence of suitable nearby red giant candidates currently makes asteroseismology the only viable method for studying these events.
This paper investigates the discovery potential of doubly charged Higgs bosons at future colliders through three-body associated production channels, demonstrating that these processes can significantly exceed conventional pair-production rates and offer viable detection prospects for --$1500$~GeV with integrated luminosities in the few ab range.
This paper proposes that long-baseline atom interferometers like MAGIS and AION can serve as sensitive non-collider probes for supersymmetric hidden sectors by detecting coherent phase oscillations induced by ultralight moduli or hidden scalars, thereby mapping these signals to fundamental parameters of supersymmetric and string-motivated theories.
This paper demonstrates that a locally static Schwarzschild spacetime can be consistently embedded within a generalized cosmological time (GCT) background with an evolving lapse by satisfying Israel junction conditions, which yield a geometric consistency condition rather than new dynamics, thereby ensuring compatibility between local gravitational stability and non-standard cosmological time normalizations.
The paper demonstrates that existing radio telescopes like CHIME and FAST can effectively detect high-frequency gravitational waves from sources such as primordial black hole mergers and ultralight boson clouds by converting them into radio photons via the inverse Gertsenshtein effect, significantly outperforming many current experiments in this frequency regime.
This paper proposes that a neighboring brane-world could communicate with ours exclusively through gravity by utilizing the Kaluza-Klein tower as a multi-input multi-output channel, where information is encoded in the occupation patterns, phases, and arrival times of massive graviton modes above a specific energy threshold.
This paper demonstrates that F-theory Grand Unified Theories impose a strict upper bound on the coupling-to-mass ratio of axion-like particles, predicting that no such particle can exist significantly above the QCD axion band in controlled regimes, thereby rendering these theories falsifiable by the discovery of axion-induced cosmic birefringence or similar phenomena.
The paper proposes that the FCC-ee can probe lepton number violation and test neutrino mass ordering through high-multiplicity final-state signatures like , which are enabled by the minimal linear seesaw mechanism to avoid suppression by small neutrino masses and yield over 1,000 expected events with negligible Standard Model background.
This paper presents an extended analysis of pseudo-scalar dark energy models, demonstrating that while axion-like potentials require large anomaly coefficients to be viable, scenarios with quadratic, linear, or Ratra-Peebles potentials can successfully explain both dark energy and cosmic birefringence with a symmetry-breaking scale near the GUT scale.
This paper demonstrates that the lower energy thresholds of Super-Kamiokande and the future Hyper-Kamiokande water Cherenkov detectors enable them to constrain previously unexplored parameter space for lighter millicharged dark matter in the Sun, offering sensitivity to fractional abundances nearly an order of magnitude below current IceCube limits.
