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 performs a coupled-channel calculation in the hidden-gauge formalism to predict five new states in the bottom sector following the discovery of , while demonstrating that the inclusion of bare components and heavy-quark-spin violating effects significantly reduces the isospin-breaking decay widths of the and states.
This paper derives joint unitarity constraints on anomalous quartic couplings arising from four-derivative effective operators in both SMEFT and HEFT frameworks, specifically analyzing their impact on off-shell Vector Boson Fusion mediated double Higgs production at high-energy colliders.
This paper proposes a novel search strategy at the High-Luminosity LHC for axion-like particles produced in association with electroweak gauge bosons, demonstrating that exploiting recoil and polarization features significantly enhances sensitivity to ALP couplings and enables discrimination between ALP and Higgs-like signals.
This paper proposes that an extremely feeble Higgs portal interaction can suppress the catastrophic overproduction of light scalar spectator dark matter generated during inflation by inducing early oscillations and reducing field variance, thereby allowing sub-GeV dark matter to constitute the observed relic abundance without thermalizing the spectator.
Using a neural-network-calibrated five-dimensional Einstein–Maxwell–dilaton holographic model, this study predicts a magnetic-field-driven critical end point at where the QCD thermal transition shifts from a crossover to a first-order phase transition, a finding that qualitatively aligns with lattice results.
This paper applies the Born-Oppenheimer effective field theory, a unified QCD-based framework derived from scale separation and symmetries, to describe the dynamics of ordinary and exotic hadrons containing two heavy quarks, specifically analyzing the , , and their bottom counterparts to elucidate the patterns of XYZ exotic states.
This paper demonstrates through lattice simulations that introducing an explicit Majorana mass to half of a Spin(10)-like generation in a four-dimensional Symmetric Mass Generation (SMG) model does not induce a seesaw mechanism or generate a light mass for the unsourced half, as the exact symmetry of the sourced action forces all unsourced mass terms to average to zero without spontaneous symmetry breaking.
This paper demonstrates that the slight breaking of scale invariance, characterized by a negative spectral index deviation, restores the renormalizability of the reheating surface volume by disrupting its fractal structure at macroscopic scales, thereby moderating the conditions for eternal inflation.
This paper investigates the stochastic completion time of first-order phase transitions in de Sitter space, demonstrating how rare ancient bubbles create an infrared-sensitive hierarchy in the power spectrum and bispectrum that is regulated by finite starting times or temporal localization, ultimately establishing a general framework for understanding curvature perturbations and non-Gaussianity.
This paper investigates the safety of spontaneous CP violation in supersymmetric models by demonstrating that while certain dynamical SUSY breaking and gaugino condensation scenarios preserve CP, others can generate dangerous complex phases in the superpotential constant or F-term, thereby reintroducing the strong CP problem through both anomaly mediation and vacuum misalignment with messenger fields.
