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 demonstrates that the QCD dipole density equations naturally yield "fan" diagrams, which are used to calculate large Pomeron loop contributions to dipole-dipole scattering, ultimately revealing that the resulting gluon distribution follows the KNO law and produces an entropy consistent with Kharzeev-Levin predictions.
This paper investigates the ATOMKI anomalies through the lens of a new 17 MeV particle with chiral couplings, finding that while the model can explain the observed signals, the preferred parameter space is in significant tension with constraints from atomic parity violation and direct electron-coupling searches, a conflict primarily driven by the specific excess observed in the transition.
This paper presents the first functional QCD calculation of the pion distribution amplitude using the functional renormalisation group and large-momentum effective theory, yielding a second-order moment of 0.267 that is significantly smaller than existing lattice results and consistent with other nonperturbative approaches.
This paper theoretically estimates the lowest boundary of the axion mass to be greater than 5.885 microelectron-Volts by analyzing the energy spectrum of electrons in magnetic fields and applying these results to hyperfine transitions in hydrogen atoms and solar axion emission.
This paper proposes a class of Composite Higgs models with a fermionic UV completion that yields a scotogenic effective theory where a stable pseudo-Nambu-Goldstone boson serves as dark matter, demonstrating through a specific example and MCMC analysis that spin-1 resonances are crucial for achieving the observed relic density and predicting distinct LHC signatures.
This paper presents the first experimental search for the -naturalness tower of neutrinos using a global analysis of public data, which successfully rules out the benchmark scenario of gauge and gravitational unification at the GUT scale () for Majorana neutrinos with a fine-tuning parameter .
This paper derives an all-order soft-collinear factorization for space-like amplitudes involving Glauber-region gluons, demonstrating their Reggeization and utilizing contour deformations to simplify the computation of collinear factorization breaking terms in multi-point amplitudes.
This paper presents a unified Khuri-Treiman formalism that combines production effects and final-state interactions to analyze COMPASS's "freed-isobar" data on the decay, successfully extracting the relative strengths and phases of production mechanisms to enable a future precise determination of the pole position.
This study employs Markov Chain Monte Carlo modeling of the Swift J1834.9-0846/W41 region's broadband spectrum to demonstrate that lepto-hadronic scenarios, particularly a two-component model where hadronic interactions dominate the extended W41 emission and a magnetar wind nebula powers the central TeV excess, provide a physically consistent explanation for the non-thermal emission that purely leptonic models cannot.
This paper revisits the search for long-lived MeV–GeV axion-like particles (ALPs) using a laser-assisted optical dump setup, extending the analysis to include both ALP-photon and ALP-electron couplings to investigate their interplay in Primakoff and Compton-like scattering processes.
