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.

Weight-Based Representation Learning for Parameter Inference in Monte Carlo Simulations

This paper introduces a machine learning framework that leverages event-level simulation weights as weak supervision signals to learn parameter-informative representations from high-dimensional data, which are then discretized into summary statistics for likelihood-based inference of physics model parameters, demonstrated through the estimation of the top quark Yukawa coupling in four-top-quark production.

Explaining the B→Kμ+μ−B \to K\mu^+\mu^- Anomaly in the Left-Right Inverse Seesaw Model

This paper demonstrates that the Left-Right Inverse Seesaw model can naturally explain the B→Kμ+μ−B \to K\mu^+\mu^- anomaly by generating a specific negative shift in the Wilson coefficient ΔC9\Delta C_9 while suppressing ΔC10\Delta C_{10} through a non-decoupling charged-scalar/heavy-neutrino box mechanism, all while satisfying stringent flavor and collider constraints.

Machine Learning Enhanced Detection of Higgs Chain Decays in Vector Boson Fusion

This paper demonstrates that advanced Deep Learning methodologies applied to low-level calorimeter data can achieve a statistical significance of approximately 4.5σ in detecting heavy CP-even Higgs boson chain decays (h2→h1h1→bbˉbbˉh_2 \to h_1h_1 \to b\bar b b\bar b) produced via Vector Boson Fusion within the Next-to-Minimal Supersymmetric Standard Model at the LHC with 300 fb−1^{-1} of integrated luminosity.

Self-gravitating quantum stars with a globally relevant Bohm potential

This paper derives a two-species Schrödinger-Poisson-Yukawa system for dark-sector fermions within an orbital-free density-functional framework, demonstrating that the Bohm potential induces a species-dependent surface-energy correction that governs the mass-radius relations of self-gravitating quantum stars and offers a predictive, first-principles method to constrain dark-fermion masses through observable astrophysical signatures.

Probing the imaginary parts and their q2q^2 dependences for the tau g−2g-2 and EDM

This paper investigates the q2q^2 dependence and absorptive imaginary parts of the tau lepton's anomalous magnetic and electric dipole moments within the SMEFT and 2HDM frameworks, demonstrating that combining measurements from Belle II and the Super Tau-Charm Facility can significantly improve current bounds and uniquely probe the energy evolution of these form factors.

Trajectories of Critical Unstable Qubits in and on the Bloch Sphere

This paper extends the study of Critical Unstable Qubits (CUQs) by employing density matrix formalism to characterize their unique indefinite anharmonic oscillations and coherence-decoherence dynamics, providing the first explicit geometric constructions of their trajectories within and on the Bloch sphere to identify stationary points and discuss implications for particle cosmology and quantum simulations.

Quantum dominance of coherent bremsstrahlung in \isotope[124]Sn+\isotope[124]Sn\isotope[124]{Sn} + \isotope[124]{Sn} scattering at 25 MeV/u

This paper presents quantum-mechanical calculations demonstrating that coherent bremsstrahlung emission overwhelmingly dominates over incoherent emission in 124^{124}Sn+124^{124}Sn scattering at 25 MeV/u, a behavior that contrasts sharply with proton-nucleus collisions and reveals a new quantum regime for studying coherent effects in heavy-ion reactions.
