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 investigates the cosmological implications of the "slingshot effect," a phenomenon where sources crossing domain walls generate confined strings, potentially sourcing gravitational waves, dark matter via Kaluza-Klein gravitons, and primordial black holes across observationally relevant mass ranges.
This paper demonstrates that extending the Standard Model with a complex scalar singlet under a local gauge group and including a dimension-six operator () enables a strong first-order electroweak phase transition over a broad parameter space, yielding observable gravitational wave signals and distinctive multi-scalar signatures at the LHC.
Using lattice QCD calculations on MILC ensembles with overlap and NRQCD actions, this study provides strong evidence for a deeply bound doubly bottom tetraquark in the isoscalar channel while finding no conclusive evidence for a bottom-strange counterpart.
This paper reviews fractional Kaehler potentials that, when combined with chaotic inflationary potentials in a non-linear sigma model, establish a class of -inflationary attractors compatible with ACT DR6 data and potentially observable tensor-to-scalar ratios, while also demonstrating their realization within supergravity via shift-symmetric Kähler potentials and monomial superpotentials.
This paper presents the first next-to-leading order study of Higgs decay into B-mesons within the general-mass variable-flavor-number scheme, demonstrating that incorporating the masses of both b-quarks and B-mesons significantly enhances the partial decay width in the low and peak scaled-energy regions, respectively, unlike previous massless approximations.
This paper investigates the two-body strong decays of pseudoscalar hidden-charm tetraquark states with specific diquark-antidiquark structures using QCD sum rules to calculate their hadronic coupling constants and total decay widths.
This paper investigates direct $CP$ violation in decays by incorporating - mixing, finding that this isospin-breaking mechanism significantly enhances $CP$ asymmetry near the resonance under specific quark composition and mixing angle conditions.
This paper proposes that the mysterious G objects orbiting the Galactic Center are remnants of neutron stars converted into low-mass black holes by captured primordial black holes, a hypothesis that simultaneously explains the objects' unique properties, the deficit of radio pulsars in the region, and offers a testable framework for probing dark matter and compact-object capture physics.
This paper demonstrates that the choice of prescription in the Collins-Soper-Sterman framework introduces a significant intrinsic theoretical uncertainty in Transverse Momentum Dependent distribution extractions, yielding consistent results for low-energy data but causing substantial discrepancies in intermediate-to-high energy predictions.
Using eROSITA-DE DR1 data, this study searches for dark matter decay signatures in the Large Magellanic Cloud, finding no evidence for sterile neutrinos or axion-like particles and consequently establishing new, stringent constraints on their mixing angles and couplings for masses below 5 keV.
