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 challenges the common assumption that large occupation numbers alone justify a classical field description for identical bosons, demonstrating instead that the validity of such a description depends critically on the quantum state's proximity to a coherent state rather than merely on the magnitude of the occupation number.
This paper extends the baryo-charmonium model to the doubly-strange sector to predict a distinct pattern of negative-parity hidden-charm pentaquarks, characterized by a near-degenerate doublet of kaon-associated states and masses consistent with recent molecular and QCD sum-rule calculations.
This paper proposes that precise measurements of total charm production in heavy-ion collisions, when combined with improved calculations of initial hard scatterings, can serve as a signature to infer properties of the pre-equilibrium stage, despite current theoretical uncertainties.
This paper presents a general framework for subtracting nonflow effects from multi-particle cumulants in small collision systems by leveraging scaling and dipolar flow estimators, thereby enabling the systematic quantification of collective flow at particle multiplicities previously inaccessible due to uncontrolled nonflow residuals.
This study employs the Faddeev approach within the Goldstone-boson-exchange relativistic constituent quark model to investigate how medium-induced parameter variations affect the mass spectrum of light and strange baryons, revealing that baryon masses are most sensitive to the quark-meson coupling constant and that even small mass shifts can significantly alter ideal-gas baryon yields.
This paper investigates the formation of light nuclei and hypernuclei in Au+Au collisions at using a parameter-free coalescence framework based on realistic -body wave functions, revealing species-dependent formation times and improving the description of yields through additional cluster-nucleon channels while providing predictions for heavier hypernuclei.
This paper calculates the axial-vector form factor for pion decay () using pseudovector coupling with a non-perturbative term and a lowest-order constant self-energy approximation, demonstrating that the inclusion of a specific parameter significantly improves the calculated values for both the axial and vector form factors.
This paper establishes the general functional form of the Euclidean energy-momentum tensor two-point function at zero and finite temperatures by decomposing it into fundamental tensorial structures, deriving differential relations via energy-momentum conservation, and expressing the full correlator in terms of a reduced set of spectral functions to facilitate more efficient lattice investigations.
This paper discusses the theoretical signatures and main QCD backgrounds of instanton (sphaleron) production events, proposing experimental searches for these unobserved phenomena via diffractive events at the LHC and spin-spin correlations between hyperons at NICA.
This paper proposes using the reconstructed invariant mass of kaons and half the deuteron four-momentum () as a direct experimental observable to distinguish between nucleon coalescence and statistical thermal models in deuteron production at the LHC, demonstrating that a resonance peak emerges only in the coalescence scenario.
