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.

Bayesian Inference of Heavy-Quark Dissipation and Jet Transport Parameters from D-Meson observables in heavy-ion collisions at the LHC energies

This study presents the first simultaneous Bayesian inference of temperature-dependent heavy-quark spatial diffusion and jet transport coefficients in quark-gluon plasma using LHC D-meson data, revealing a non-monotonic temperature dependence in their ratio and establishing a data-driven quantitative relationship between these fundamental transport properties.

Exact black holes and black branes with bumpy horizons supported by superfluid pions

This paper presents exact solutions for bumpy black holes and black branes in the Einstein $SU(2)$ non-linear sigma model, where superfluid pion multi-vortices induce horizon deformations governed by a Liouville equation and characterized by a topological vorticity invariant that dictates the geometry and thermodynamics.

Beyond the Dilute Instanton Gas: Resurgence with Exact Saddles in the Double Well

This paper demonstrates that by utilizing exact finite-temperature saddles and a Picard-Lefschetz contour integral framework involving Weierstrass elliptic functions and Lamé operators, one can systematically compute the full resurgent structure of the double-well partition function and energy levels for all excited states, thereby overcoming the limitations of the traditional dilute instanton gas approximation.

Probing Neutrino Compositeness with Invisible and Displaced Signals

This paper proposes that neutrinos may couple to an interacting sterile sector, leading to "dark jet" signatures such as displaced vertices and emerging jets in high-energy neutrino beams, which offer unique sensitivity to neutrino compositeness beyond current constraints from meson, electroweak, and Higgs decays.

A Busy Higgs Signal

This paper proposes a mechanism within effective field theory where higher-order Higgs couplings violate the conventional Goldstone Equivalence Theorem expectations, selectively amplifying Higgs-rich final states (such as multi-Higgs, $ht$, and $Zh$) to become the dominant discovery channels for heavy resonances beyond the Standard Model.

Entropy considerations in Many-Body Gravity and General Relativity, and the impact on cosmic inflation

This paper demonstrates that Many-Body Gravity (MBG), a modified 5-D gravity theory, naturally reproduces cosmic inflation and resolves time-definition issues in non-interacting universes by utilizing entropic terms and interacting massless scalar fields, all without requiring dark matter.

An efficient Wavelet-Based Hamiltonian Formulation of Quantum Field Theories using Flow-Equations

This paper proposes an efficient framework for analyzing quantum field theories by combining a Daubechies wavelet basis with Similarity Renormalization Group flow equations to systematically decouple degrees of freedom across scales, thereby enabling the extraction of low-energy spectra from reduced-resolution Hamiltonian blocks with significantly lower computational cost.

Inflaton Regeneration via Scalar Couplings: Generic Models and the Higgs Portal

This paper demonstrates that for inflationary models with monomial potentials $V(\phi) \propto \phi^k$ ( $k \ge 4$ ), the inflaton's asymptotically vanishing mass allows it to be regenerated from the thermal plasma long after reheating, offering a new framework to constrain reheating mechanisms and potentially explain dark matter.

Exploring non-equilibrium effects in sequential freeze-in

This paper investigates non-equilibrium effects in a two-scalar sequential freeze-in dark matter model, demonstrating that full phase-space treatments can yield relic abundance predictions deviating by up to an order of magnitude from traditional number-density approaches, thereby underscoring the necessity of advanced numerical tools for accurate multi-component dark sector modeling.

Charmed baryon decays at BESIII

This paper summarizes recent BESIII results on charmed-baryon decays derived from the world's largest sample of $\Lambda_c^+\bar{\Lambda}_c^-$ pairs, highlighting the observation of the rare semi-leptonic decay $\Lambda_c^+\to ne^+\nu_e$ , the first measurement of the decay asymmetry in $\Lambda_c^+\to\Xi^0K^+$ , and various branching fraction measurements and partial wave analyses.
