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 reviews Bayesian models for estimating uncertainties from missing higher-order perturbative predictions and demonstrates how modifying their likelihoods and priors can yield smooth, quasi-Gaussian probability distributions that better align with standard physics analysis assumptions.
This study utilizes the (1+1)-dimensional Dirac-Heisenberg-Wigner formalism to demonstrate that super-Gaussian pulse shapes, frequency chirping (particularly of the weak component or both components), and relative phase in spatially inhomogeneous electric fields significantly enhance and reshape dynamically assisted electron-positron pair production, offering key parameters for optimal control of the process.
This paper presents a systematic study of semileptonic decays of various heavy vector mesons within the Hard-Wall AdS/QCD framework with , calculating transition form factors and branching ratios for multiple decay modes across four quark-level transitions to explore flavor dynamics and test the Standard Model.
This paper challenges the misconception that the dark matter mass is the sole relevant scale in low reheating temperature scenarios, demonstrating that the maximum temperature limits thermal production efficiency and establishes a minimum reheating temperature below which the dark matter relic abundance becomes negligible for both freeze-in and freeze-out mechanisms.
Using a large- expansion to next-to-leading order, this paper computes universal scaling exponents for massless scalar field theories far from equilibrium, revealing distinct nonthermal fixed points with power-law tails for energy transport and for effective particle number transport, thereby establishing that relativistic and nonrelativistic theories with linear dispersions belong to different universality classes.
This paper presents a model-independent analysis of the LUX-ZEPLIN experiment's high-energy nuclear recoil candidate, demonstrating that while inelastic dark matter with specific mass and splitting parameters can naturally explain the event's location, the associated kinematic suppression and Helm form factor effects create tension with sideband data, suggesting that a dedicated search in the 271–800 keV range is necessary to decisively test this hypothesis.
This paper investigates how particle production driven by temporarily tachyonic masses during strongly supercooled cosmological phase transitions diverts energy from gradient motion, thereby altering gravitational-wave spectra, modifying bubble dynamics, and potentially facilitating primordial black hole formation.
This paper investigates how coherent forward scattering of high-energy neutrinos off dark matter in spikes around supermassive black holes induces flavor-dependent potentials that significantly alter neutrino flavor compositions at Earth, offering a novel method to probe neutrino-dark matter interactions through IceCube measurements.
This paper establishes a threshold resummation framework for computing large- parton distribution functions via large-momentum effective theory by factorizing the matching coefficient into a space-like jet function and heavy-light Sudakov form factors, thereby enabling direct lattice QCD calculations of these critical distributions with NNLO consistency.
This paper addresses the environmental responsibility of the HECAP+ scientific communities by analyzing the ecological impacts of their shared research infrastructure and data processing, while proposing best practices and recommendations to enhance sustainability and social accountability.
