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 establishes that the practical limits of coherent enhancement in detectors are fundamentally constrained by entanglement, deriving general bounds that link the strength of coherent effects to the detector's single-mode entanglement entropy across both metrology and scattering contexts.
This paper investigates electroweak restoration in longitudinal di-boson production by comparing Standard Model Effective Field Theory (SMEFT) and Higgs Effective Field Theory (HEFT), demonstrating that specific amplitude ratios distinguish the two frameworks and proposing the to cross-section ratio as a key observable for future HL-LHC sensitivity studies.
This paper investigates the sensitivity of the future Compact Linear Collider (CLIC) to lepton flavor violating Higgs decays (, , and ), projecting that it could establish 95% confidence level upper limits on their branching fractions between and using integrated luminosities of 4 ab at 1.4 TeV and 5 ab at 3 TeV.
This paper proposes a framework for understanding scientific rewards in physics by characterizing highly recognized contributions as transformative actions—such as expansion, contraction, reconfiguration, or enabling—that reshape the landscape of empirically viable theories, with the magnitude of reward correlating to the scope, centrality, depth, and future leverage of these transformations.
This paper investigates the reciprocal symmetry of charged-particle multiplicity distributions in proton-proton collisions by deriving higher-order local constraints and an entanglement entropy formula, finding that while the symmetry holds approximately near the mean multiplicity, it breaks down globally at 13 TeV due to residual deviations exposed by high-precision data.
This paper extends previous work by deriving consistent expressions for the longitudinal, singlet, and gluon structure functions (, , and ) directly from the measured and its logarithmic derivative with respect to , while treating small non-singlet corrections at low .
This paper employs machine learning optimization techniques, specifically the Adam optimizer, to navigate the complex 33-dimensional parameter space of a supersymmetric GUT extended with and Higgs representations, successfully identifying Yukawa coupling configurations that suppress dimension-five proton decay to satisfy Super-Kamiokande's experimental bounds.
This paper demonstrates that within a general low-energy effective field theory, a massless complex scalar pair coupled via a purely left-handed vector current is the unique nonstandard invisible sector capable of exactly mimicking the Standard Model's Michel distribution in lepton decays, while all other higher-spin or interaction scenarios remain distinguishable.
This paper investigates the physical constraints imposed by energy-momentum conservation on ortho-positronium three-photon decays and presents a closed-form analytical method for reconstructing the annihilation vertex based on energy measurements.
This paper presents an iterative algorithm for the symbolic reduction of multi-loop Feynman integrals by reformulating integration-by-parts identities as differential equations for sector-wise generating functions within a non-commutative algebra, thereby unifying the derivation of reduction rules and completeness criteria.
