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 dynamical mechanism where a new scalar field induces a transient bias to trigger the decay of CP domain walls formed by spontaneous CP violation, thereby resolving the associated cosmological constraint while simultaneously providing a dark matter candidate through the field's coherent oscillations.
This paper presents a comprehensive spin density matrix analysis of polarization transfer in polarized collisions producing decays into octet baryon-antibaryon pairs, confirming theoretical predictions for angular distributions and demonstrating how longitudinal beam polarization at future facilities like the STCF can serve as a new experimental tool to test decay mechanisms and explore baryonic spin entanglement.
By combining DESI DR2 clustering data with NuFIT oscillation results, this study demonstrates that cosmological evidence has transitioned from prior sensitivity to decisive, likelihood-dominated exclusion of the inverted neutrino mass hierarchy, strongly favoring the normal ordering and predicting an effective Majorana mass in the few-meV regime.
This paper computes the one-loop mixing of bosonic and two-fermion interactions into two-fermion operators at dimension eight in the SMEFT, completing all such mixing calculations except for the four-fermion to two-fermion sector.
This paper proposes using a tons-scale hydrocarbon scintillator detector at the Spallation Neutron Source to search for sub-GeV dark sector particles, such as axion-like particles and heavy neutral leptons, produced in muon decays, demonstrating the potential for order-of-magnitude sensitivity improvements over current limits through effective cosmic ray background rejection.
Using the curl-mode CMB lensing power spectrum from the Atacama Cosmology Telescope DR6 data, the study establishes the tightest constraints to date on cosmic string tension and inter-commutation probability, improving previous limits by nearly an order of magnitude.
This paper derives unrenormalized tree-level weak boson parton densities for leptons and hadrons within the Effective Approximation, introduces kinematical consistency conditions to resolve theoretical pathologies, and demonstrates that these conditions enable accurate approximations of multi-leg processes while suggesting the feasibility of testing the framework with same-sign scattering data at the LHC.
This paper proposes a predictive neutrino mass matrix texture with specific correlations, realized within a type-I and type-II seesaw framework governed by an symmetry group, which addresses key phenomenological issues and demonstrates stability under renormalization group evolution.
This paper reviews Pati-Salam models derived from the spectral action principle in noncommutative geometry, which feature gauge coupling unification and limited scalar content, with a specific focus on the phenomenological implications of the scalar leptoquark for guiding future collider searches.
This paper proposes a one-loop radiative neutrino mass model featuring singlet-doublet dark matter and -odd scalars, demonstrating that quartic Higgs-scalar interactions can induce a first-order phase transition producing observable gravitational waves while simultaneously satisfying constraints from neutrino mass, the muon anomalous magnetic moment, and lepton flavor violation.
