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 proposes a mechanism where axion-like particles coupled to the Nieh-Yan term generate a chiral gravitational wave background through tachyonic instability during the radiation-dominated era, offering a new avenue for detecting these particles via pulsar timing arrays and space-based observatories.
This paper presents a complete one-loop dictionary connecting the Standard Model Effective Field Theory to arbitrary ultraviolet completions involving heavy fermions and scalars, implemented in the updated SOLD package to facilitate systematic phenomenological studies such as explaining the measurement tension.
This paper demonstrates that naturalness scenarios naturally suppress neutrino masses through a mechanism involving numerous mixing partners, leading to a specific tower of additional neutrino mass eigenstates that offers unique, testable signatures in terrestrial oscillation, mass, and neutrinoless double beta decay experiments, thereby extending the model's phenomenological reach beyond cosmology.
This paper introduces a new thermodynamic state function to compute high-order temperature fluctuations in hot QCD matter, revealing that these fluctuations are significantly suppressed and exhibit negative skewness during the transition from a hadron resonance gas to a quark-gluon plasma due to the increased heat capacity of the latter.
This paper presents a hybrid numerical analysis demonstrating that the collision of sound shells generated by large primordial density perturbations produces a stochastic gravitational wave background with detectable signatures for future observatories, offering new constraints on primordial black holes even after they have evaporated.
This paper demonstrates that next-generation gravitational wave detectors with enhanced high-frequency sensitivity can distinguish between binary neutron star and low-mass black hole mergers during the late inspiral and postmerger phases, thereby enabling the disentanglement of their respective merger rates and placing constraints on heavy, non-annihilating dark matter interactions that could cause neutron stars to collapse into transmuted black holes.
This paper compares nonfactorizable charm-quark loops in exclusive FCNC decays with three-particle contributions to semileptonic -decay amplitudes, highlighting that while both are described by a convolution involving the -meson's three-particle wave function in the heavy-quark limit, they differ fundamentally in their light-cone configurations (double collinear versus single collinear).
This paper proposes using lattice simulations to directly calculate the energy density spectra of scalar-induced gravitational waves with non-Gaussianity up to all orders, revealing that even modest non-Gaussianity significantly alters ultraviolet behaviors and necessitates careful consideration for future detections and primordial black hole constraints.
This paper generalizes spurion analysis to non-invertible fusion algebras, specifically near-group types like Fibonacci and Ising, by introducing a systematic labeling scheme for coupling constants that explains the radiative violation of tree-level selection rules and distinguishes these effects from those arising in lifted group symmetries.
This paper introduces a renormalization-group invariant mean-field approach to the Parity-Doublet Model that incorporates baryonic vacuum contributions, enabling a consistent analysis of chiral symmetry restoration in nuclear and neutron-star matter across relevant densities and temperatures.
