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.

Collective excitations in magnetic topological insulators and axion dark matter search

This paper investigates collective excitations in magnetic topological insulators and finds that one identified "axionic" quasi-particle has an electromagnetic coupling that is either unchanged or suppressed by up to two orders of magnitude compared to previous estimates, significantly altering the sensitivity prospects for axion dark matter searches using these materials.

Muon Beam Dump Experiments explicate five-dimensional nature of U(1)LμLτU(1)_{L_{\mu}-L_{\tau}}

This paper investigates how present and future muon beam dump experiments can probe the five-dimensional nature of U(1)LμLτU(1)_{L_\mu-L_\tau} interactions by leveraging the enhanced signals from multiple Kaluza-Klein gauge bosons and their distinct decay channels to provide direct evidence for extra dimensions while constraining parameters via the muon (g2)(g-2) anomaly.

Inclusive J/ψJ/ψ productions in pp collisions at s=\sqrt{s}= 5.02, 7, and 13 TeV with the PACIAE model

This study utilizes the PACIAE 4.0 model, which incorporates both color-singlet and color-octet NRQCD contributions alongside cluster collapse and bb-hadron decays, to successfully simulate inclusive J/ψJ/\psi production in proton-proton collisions at 5.02, 7, and 13 TeV and provide a quantitative analysis of the relative contributions and rescattering effects across various production mechanisms.

New Physics Searches via Beam Normal Spin Asymmetry in Bhabha Scattering

This paper investigates the sensitivity of the beam normal spin asymmetry in Bhabha scattering to beyond-the-Standard-Model mediators within the JLab polarized positron program, highlighting how the observable's unique zero crossing in the Standard Model provides a clean, background-free opportunity to significantly extend search ranges for scalar and vector new physics scenarios.
