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 investigates the thermal history, relic density, and indirect detection signatures of complex scalar dark matter that forms bound states called "SIMPonium," concluding that the resulting photon flux is too weak to be detected by current experimental facilities.
This paper investigates the internal structure of the meson using a quark model and proposes that its transverse momentum distributions and yields in relativistic heavy ion collisions can be used to distinguish whether it is a charmonium, a tetraquark, or a hadronic molecular state.
This paper demonstrates that for high-energy neutrinos, the interplay between anisotropic Lorentz invariance violation and Earth's matter potential produces unique, observable signatures—such as direction-dependent resonances and altered neutrino-antineutrino symmetry—that are absent in vacuum-based models.
The paper proposes that dark matter originates from primordial black holes formed by regions of eternal inflation that failed to reheat, a mechanism that predicts a specific spectrum of curvature perturbations and a detectable stochastic gravitational wave background.
This paper investigates a two-component dark matter model featuring a singlet scalar and a Majorana fermion under symmetry, demonstrating that the FIMP relic density can be successfully achieved across various mass hierarchies even when certain couplings are as small as .
This study demonstrates that incorporating nonextensive statistical mechanics into a kinetic theory framework significantly enhances the collisional energy loss of heavy quarks in a quark-gluon plasma, with the magnitude of this effect depending on the nonextensive parameter , the quark's momentum, and the specific theoretical formalism used.
This paper presents EPOS4 model predictions for pp, O-O, and Pb-Pb collisions at LHC Run 3 energies, demonstrating that the dynamical core-corona approach and hadronic-phase effects (via UrQMD) are essential for describing the non-universal scaling of transverse momentum, identified-hadron spectra, and nuclear modification factors across different system sizes.
This paper calculates next-to-leading power QCD factorization expressions for the form factors and uses light-cone sum rules to estimate their soft contributions, demonstrating that these contributions are more theoretically controllable at mildly spacelike photon virtualities.
This paper presents an updated analysis of the Borexino Phase-III data set to provide improved constraints on flavor-diagonal non-standard neutrino interactions and offers a first-of-its-kind comprehensive exploration of all possible off-diagonal NSI terms.
This paper demonstrates that primordial features in the Cosmic Microwave Background, such as sharp signals and clock signals, can serve as unique observational probes to detect the high-energy physics of the Affleck-Dine baryogenesis mechanism by identifying correlated imprints in both curvature and baryon-density isocurvature perturbations.
