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 employs dynamical systems analysis to demonstrate that an initial population of NS5-brane wrapped strings can resolve the cosmological overshoot problem for the volume modulus by transferring energy to it, while simultaneously predicting a potentially detectable gravitational wave signal from the resulting high energy density of cosmic superstrings during modulus oscillations.
This study utilizes Monte Carlo simulations based on the Color Glass Condensate formalism to demonstrate that multiplicity distributions in proton-proton and proton-lead collisions can distinguish between different initial-state proton geometries, specifically testing the three-quark Y-shape baryon junction model, while highlighting the critical importance of accounting for intrinsic saturation scale fluctuations.
This paper investigates inflation in composite pseudo-Nambu-Goldstone boson models where non-minimal coupling induces ultra-slow-roll dynamics, predicting the formation of ultra-light primordial black holes as potential dark matter candidates and a high-frequency gravitational wave signal that motivates the development of future detectors capable of probing currently inaccessible frequency regimes.
This paper proposes a method to construct the equation of state for supra-saturation density nuclear matter by modeling nucleons as topological solitons within a bosonized Nambu-Jona-Lasinio framework, demonstrating that the dynamical restoration of chiral symmetry leads to a stiffened equation of state compatible with neutron star observations.
This paper determines the four-loop structure of Abelian and non-Abelian non-global logarithms for dijet invariant mass using the Cambridge/Aachen algorithm, demonstrating that it minimizes these logarithmic effects compared to anti- and clustering schemes.
This paper proposes that a metastable, gravitationally trapped "fireshell" of photons and electron-positron pairs around a black hole horizon can accelerate charged particles to ultra-high energies via the Compton-rocket effect and avalanche runaway processes, potentially serving as a source for very-high-energy photons and neutrinos.
This paper proposes a method using Recursive Jigsaw Reconstruction, enhanced by two new variables, to effectively reconstruct the toponium bound state near the threshold region and improve sensitivity to its signal based on recent ATLAS and CMS findings.
This paper proposes using Recursive Jigsaw Reconstruction within the MadGraph5_aMC@NLO framework to resolve combinatorial ambiguities and reconstruct toponium states at the LHC's threshold, demonstrating that specific angular variables can enhance signal sensitivity by up to 15% compared to current strategies.
This study demonstrates that applying the Medium Separation Scheme (MSS) alongside Magnetic Field Independent Regularization (MFIR) to the Nambu--Jona-Lasinio model of magnetized two-flavor color superconducting quark matter eliminates unphysical oscillations and ensures positive magnetization, thereby correcting artifacts found in traditional approaches that fail to properly separate medium effects from vacuum contributions.
This study analyzes gravitational-wave signals from two 3D core-collapse supernova simulations of massive progenitors with vigorous pre-collapse shell activity, finding that while the resulting signals are detectable by current and future interferometers, they lack unique features directly attributable to the pre-collapse dynamics despite exhibiting distinct characteristics compared to previous models.
