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 while a derivation of flavor neutrino propagators without perturbation treatment violates fundamental quantum field theory principles, an effective propagator can be constructed by treating mass mixing as a perturbation, thereby successfully rederiving neutrino oscillation probabilities in both vacuum and matter.
This paper calculates the magnetic moment of the hadron using a non-relativistic quark model with a realistic three-body force to demonstrate that the resulting value can qualitatively distinguish between pure color-singlet (molecular-like) and compact internal configurations, despite the model's inability to fully capture extended molecular dynamics.
This paper presents the first numerical evaluation of the Standard Model-induced -odd form factor in the vertex, revealing that its quark loop contributions are negligible () and far below current experimental sensitivity, while also analyzing its phenomenological implications through asymmetries in three-body decays.
This paper presents an efficient block encoding algorithm for the plaquette operator in the irreducible representation basis of non-Abelian lattice gauge theories, overcoming previous scaling limitations by leveraging matrix element factorization, classical precomputation, and quantum oracles.
This paper investigates the forward-backward asymmetry in the decay induced by complex form factors, deriving constraints on the CP-violating parameter from LHC data that are comparable to electric dipole moment limits and predicting an asymmetry of order potentially accessible at the HL-LHC.
This paper identifies significant deviations in high-energy tree-level scattering rates within thermal QCD compared to standard approximations, revealing that these discrepancies bias current jet-medium transport coefficient () constraints and providing a framework to quantify the resulting theoretical systematic uncertainty for Bayesian analyses in Monte Carlo simulations.
This paper revisits tree-level gluon-gluon scattering in thermal QCD to identify deviations from standard approximations, thereby establishing a framework for quantifying theoretical systematic uncertainties to improve Bayesian jet-medium Monte Carlo simulations.
This paper presents a response to a comment on the authors' previous work regarding constraints on neutrino-dark matter interactions derived from IceCube observations of active galactic nuclei.
This paper investigates lepton flavor violating decays within the vector-like fermion model, demonstrating that specific parameter regions allow branching ratios large enough to be detectable by future experiments.
The paper argues that Ostrogradsky's theorem, which predicts unstable ghost modes in higher-derivative systems, does not apply to background-independent quantum gravity because the Hamiltonian constraint forces the total energy to vanish, thereby reinterpreting the ghost mode as a necessary component of spacetime construction, while noting that the theorem remains valid only within background-dependent weak-field approximations below the Planck scale.
