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 study utilizes radiative general relativistic magnetohydrodynamic simulations to demonstrate that neutron star ultraluminous X-ray sources can be explained by weaker magnetic fields and higher accretion rates, which enhance outflow power and beaming to produce apparent luminosities consistent with observations despite lower intrinsic radiation efficiency.
This paper demonstrates the application of Truncated Marginal Neural Ratio Estimation (TMNRE) within the Swyft framework to constrain axion-like particle parameters using simulated Cherenkov Telescope Array observations of NGC 1275, showcasing a robust alternative to standard likelihood-based methods for handling complex models with numerous nuisance parameters.
This paper argues that the conventional definition of a Majorana fermion as a single chiral field plus its charge conjugate is inconsistent with the absence of Majorana-Weyl fermions in four dimensions, proposing instead that true Majorana fermions in the type I seesaw model arise only through a Bogoliubov transformation of chiral fields, a distinction that has direct implications for neutrinoless double beta decay.
This paper explores how quantum reference frames define rest frames for mixed particles and investigates the resulting frame-dependent entanglement and its phenomenological consequences for neutral mesons and neutrinos.
This paper investigates Lorentz- and CPT-violating effects in neutron and storage-ring electric dipole moment experiments using the Standard-Model Extension framework to derive spin-precession modifications and establish correspondences between measured EDMs and specific SME coefficients, thereby enabling the setting of new limits on previously unconstrained Lorentz-violating parameters.
This paper proposes a novel machine-learning-enhanced strategy using gradient-boosted decision trees to probe heavy neutrinos with non-universal couplings across a mass range of 50 GeV to 10 TeV at the High-Luminosity LHC, demonstrating sensitivity to mixing parameters between and 1 by leveraging both -channel and vector boson fusion production mechanisms.
This study proposes a new Clauser-Horne inequality for higher-order statistical moments to demonstrate significant violations of third-order quantum correlations in entangled hyperon-antihyperon systems produced in charmonium decays, offering a viable method for experimental verification at facilities like BESIII and Belle II.
This paper proposes a generic axion-driven cogenesis scenario within a Type-I seesaw and DFSZ framework, where Hubble-induced masses and PQ-violating operators trigger early axion rotation to simultaneously generate the baryon asymmetry and dark matter abundance via kinetic misalignment, all while satisfying strong CP constraints and isocurvature limits.
This study uses numerical simulations to demonstrate that the fate of compact stellar systems in ultralight dark matter halos is determined by a competition between internal relaxation-driven core collapse and ULDM-induced heating, leading to either survival or disruption depending on the system's size and establishing a new evolutionary phase diagram for robust dark matter constraints.
This paper demonstrates that the supersymmetric expansion algorithm can efficiently derive Rayleigh-Schrödinger perturbation theory results for energy and eigenstate corrections without summing over intermediate states, instead expressing them as integrals weighted by the probability densities of edge states.
