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 explores a framework for gauge coupling unification using non-renormalizable operators in $SU(5)$, demonstrating that while fermion condensates in the 5 representation fail due to proton decay constraints, viable models achieving both unification and doublet-triplet splitting can be constructed using condensates in the 10 and 24 representations.
This study demonstrates that using transverse spherocity to classify Pb+Pb collisions into isotropic and jetty topologies provides a cleaner and more reliable method for probing the Chiral Magnetic Effect by effectively suppressing flow-driven and resonance-decay backgrounds compared to traditional flow-vector-based approaches.
This paper investigates pion valence quark parton distribution functions using a light-cone quark model, demonstrating that the evolved distributions and predicted structure functions align well with experimental data from DESY-HERA and theoretical extractions while also providing predictions for future electron-ion collider kinematics.
This paper demonstrates that superpositions of toroidal electromagnetic pulses propagating in free space naturally generate localized regions where , thereby producing a co-propagating, space-time localized pseudoscalar field within the framework of axion electrodynamics, distinct from the physical creation of axion particles.
By jointly analyzing DESI DR2, Pantheon+, and Cosmic Chronometers data, this study finds that dynamical dark energy models with a time-varying equation of state provide a better fit and are favored over the standard CDM model, though current constraints remain moderate and future high-precision observations are needed for definitive conclusions.
This paper calculates the resummed perturbative free energy of four-dimensional supersymmetric Yang-Mills theory to order in the 't Hooft coupling, demonstrating that all infrared divergences cancel, comparing different regularization schemes and Padé approximants, and showing that the theory exhibits superior convergence properties compared to QCD.
This paper introduces a novel, model-agnostic Monte-Carlo event generation framework for X-ray Thomson scattering analysis that samples individual scattering events from differential cross sections to bypass computationally expensive forward modeling, thereby enabling statistically consistent, geometry-aware, and scalable diagnostics for warm-dense matter experiments.
This paper demonstrates that future Higgs factories, particularly when utilizing the ILD detector concept and accounting for challenging "worst-case" scenarios involving low cross-sections, small mass differences, and specific beam backgrounds, can achieve nearly kinematic-limit exclusion and discovery reaches for light stau pair production, outperforming current LEP and LHC constraints.
This paper proposes a non-unitary, pseudo-hermitian model of two coupled Higgs doublets in four dimensions that exhibits cyclic renormalization group flows and "Russian Doll" scaling of vacuum expectation values, potentially offering a novel explanation for the three families of Standard Model particles and the hierarchy problem.
This paper proposes a six-dimensional $SO(20)$ gauge theory with a single spinor fermion that, upon compactification to five dimensions, successfully unifies the Standard Model Higgs field and three generations of quarks and leptons into a single geometric and algebraic framework.
