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 parton shower event generators offer a more accurate description of dilepton spectra from photon conversion in heavy-ion collisions compared to the traditional Kroll-Wada approach, particularly at larger invariant masses where they better account for phase-space suppression, recoil kinematics, and higher-order corrections.
This paper presents a phenomenological study of the symmetric Type-Z Three Higgs Doublet Model at a 1000 GeV International Linear Collider, demonstrating that specific production channels involving heavier Higgs bosons offer promising opportunities to discover new physics beyond the Standard Model.
This paper investigates whether small dark matter clumps passing near Earth could generate the gravitational-wave glitches observed in LIGO/Virgo/KAGRA data, finding that while most glitches are inconsistent with this hypothesis, the analysis establishes the first direct upper limits on the local over-density of such dark matter clumps.
This paper proposes that the Cherenkov Telescope Array (CTA) can detect gamma-ray signatures from strangelets potentially emitted by the exotic strange quark star candidate HESS J1731-347, thereby validating the existence of strange quark matter and its role in cosmic-ray acceleration.
This paper systematically investigates the mass spectra and decay channels of fully heavy tetraquark states using a diquark-antidiquark model, concluding that while , , and are unlikely to be -wave fully charmed tetraquarks, is a strong candidate for the state and predicting several narrow states for future experimental observation.
This paper utilizes a semi-analytical model of galaxy and supermassive black hole evolution within the CDM paradigm to demonstrate that the observed stellar mass–black hole mass relation at high redshifts disfavours fuzzy dark matter fields with masses below eV and warm dark matter particles with masses below 7.2 keV at the 95% confidence level.
This paper demonstrates that embedding natural inflation within Palatini gravity, specifically with the model where , restores its consistency with observational data, whereas models with fail to provide comparable improvements.
Using dispersion theory to account for strong pion-pion final-state interactions, this study demonstrates that the substructure near the threshold in decays can be reproduced without invoking an extra resonance, attributing the observed dip primarily to a helicity-flip amplitude rather than the virtual exchange of the state.
Using the covariant four-dimensional Bethe-Salpeter equation with an infrared-finite QCD running charge, this study determines a scale-dependent effective charm quark mass (ranging from 1.1 to 1.5 GeV) that successfully reproduces experimental leptonic decay constants for excited charmonium states with unprecedented theoretical precision.
This paper proposes a quantum-gravitational framework based on Schwarzian theory and ensemble averaging to resolve the cosmological constant problem by deriving the observed dark energy density and equation of state from the ensemble average of time-reparametrization modes.
