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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper re-evaluates Standard Model vacuum stability using high-order perturbations and precise parameters to show that improved measurements of the top mass and strong coupling could confirm stability at the level, while also exploring viable singlet scalar extensions that remain stable up to the Planck scale and predicting significant deviations in Higgs couplings testable at current and future colliders.
This paper reaffirms the robustness of strong experimental constraints on light neutralino thermal dark matter within the phenomenological MSSM, explores the impact of light staus and non-standard cosmology, and proposes machine learning-optimized benchmarks for future LHC Run-3 searches.
This paper advocates for a Bayesian statistical framework based on timescale analysis to derive the most rigorous constraints on ultralight boson masses and self-interactions from black hole spin measurements, demonstrating its application to both stellar-mass and supermassive black holes while highlighting the need for standardized data sharing in the field.
This paper proposes and validates a Pearson correlation between spectator and charged-particle forward-backward asymmetries as a robust, data-driven observable to constrain models of preferential emission and spectator breakup dynamics in heavy-ion collisions.
This paper reviews the analytically derived phenomenon of spontaneous magnetization in quark-gluon plasma at high temperatures, where color and usual magnetic fields are simultaneously generated and stabilized by an condensate, potentially offering observable signals for QGP creation in heavy ion collisions.
This paper employs QCD sum rules to systematically analyze D-wave charmonium states, predicting masses that align with recent experimental observations of , , and while also estimating the mass of the yet-unobserved state.
This paper investigates (3+1)d topological orders with anomalous symmetry by microscopically constructing symmetry-preserving gapped boundary states for related (4+1)d SPT phases, demonstrating that such states admit a topological gauge theory description when , a non-TQFT solution when , and no symmetric gapped state otherwise, thereby confirming existing no-go theorems.
This paper revisits the stability of the Higgs potential in the Standard Model by leveraging high-precision theoretical calculations and recent experimental data to demonstrate the critical role of top quark mass and strong coupling constants, while also exploring new physics scenarios that could ensure absolute stability.
This study evaluates the potential of the IDEA detector at the FCC-ee, alongside proposed dedicated LLP detectors like DELIGHT B, to detect long-lived particles arising from Higgs and B-meson decays within a Higgs portal model, finding that cylindrical configurations and DELIGHT B offer enhanced sensitivity against Standard Model backgrounds.
Using Pantheon+, DESy5, and DESI-DR2 data, this study finds that generalized entropic gravity-thermodynamic models are significantly disfavored compared to the standard CDM model, with the data favoring standard Bekenstein-Hawking entropy and a three-parameter formulation over more complex variants.
