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 resolves the tension between local Markovian string-breaking dynamics and global conservation constraints in hadronization by recasting the process as a conditioned stochastic diffusion, where conservation laws induce non-Markovian correlations that are exactly absorbed via a Doob -transform to establish a systematic tower of effective field theories with Wilsonian structure.
This paper provides an introduction and overview of light meson form factors, covering their classical and quantum field theory foundations, main theoretical methods, and specific discussions on pion, kaon, eta, and eta' form factors.
This paper demonstrates that Big Bang nucleosynthesis constraints on GeV-scale heavy neutral leptons within the neutrino-extended Standard Model Effective Field Theory provide a crucial upper bound on the theory's cutoff scale for masses above 100 MeV, thereby defining specific target regions for future laboratory searches.
This paper reports the most precise theoretical predictions for the total cross section at the LHC, combining NNLO QCD corrections with NNLL soft-gluon resummation and complete NLO electroweak corrections.
This paper proposes a minimalistic model containing four scalar multiplets to simultaneously explain multiple excesses observed at the LHC (notably at 95 GeV and 650 GeV), arguing that these hints disfavor common scalar extensions while predicting specific charged scalars that make the theory testable and falsifiable despite current data limitations.
This paper proposes "blast-frozen dark matter," a scenario where a first-order phase transition rapidly generates dark matter mass and induces distinctive oscillations in density perturbations that could be detected by next-generation cosmological surveys.
This paper presents a novel likelihood framework that utilizes the high-energy KM3-230213A neutrino event alongside multi-messenger constraints to establish the most stringent limits to date on super-heavy dark matter lifetimes () while highlighting the critical potential of galactic neutrino flux measurements for future dark matter research.
Using the PACIAE 4.0 model, this study proposes that the newly observed particle could be a -wave meson, an -wave tetraquark, or a hadro-strangeonium state, and distinguishes these candidates by calculating their production rates and kinematic distributions in collisions.
This study investigates the impact of early-time charm quark dynamics on D-meson observables in Pb+Pb collisions at TeV using the IP-Glasma+MUSIC+UrQMD framework and finds that despite significant momentum broadening in the pre-equilibrium stage, the nuclear modification factor () and elliptic flow () of D-mesons remain only weakly sensitive to these early interactions.
This study employs a refined AMPT transport model with adjusted beauty quark mass and flavor-specific coalescence parameters to successfully reproduce LHCb and ALICE data on beauty and non-prompt charm hadron production in 13 TeV $pp$ collisions, offering new insights into heavy quark dynamics and hadronization mechanisms in small collision systems.
