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 dynamics of multi-axion quintessence models, finding that while multiple interacting axion fields can produce diverse dark energy behaviors, their prior probability distributions generally move further away from current DESI observations compared to simpler single-field models, suggesting they are not generically preferred unless exotic evolution is detected.
This paper establishes a quantitative framework linking local spin polarization and quantum entanglement in two-qubit systems by deriving a closed-form upper bound on concurrence that is saturated by pure states, and demonstrates its application to the process where polarization significantly constrains maximal entanglement.
This paper proposes a non-relativistic cosmological collider framework where a massive tilted-ghost spectator field generates distinctive squeezed-limit non-Gaussianity through propagation-induced mode deformations rather than boost-breaking interactions, effectively mimicking boostless collider signals via a unique chemical-potential-like mechanism.
This paper proposes a geometric flavor mechanism driven by a topological condensation that balances continuous and discrete vacuum sectors to naturally derive the Koide relation and explain the charged lepton mass hierarchy.
This paper introduces the Normalized Autoencoder (NAE) to provide a statistically interpretable, probabilistic framework for neural anomaly detection in new physics searches, demonstrating its validity through toy models, jet analysis, and Bayesian uncertainty quantification.
This paper utilizes solar neutrino data from the SOHO observatory to derive significantly improved constraints on the mixing between heavy neutral leptons and tau neutrinos in the MeV mass range, surpassing existing terrestrial limits by more than an order of magnitude.
This paper presents a statistical framework to forecast detectable subhalo impacts on Milky Way stellar streams using LSST and Via data, identifying five promising streams with significant expected impact rates and demonstrating how such observations can constrain dark matter particle properties across different cosmological models.
This paper presents the first application of unbiased exponential resummation to (2+1)-flavor lattice QCD at physical quark masses, yielding consistent determinations of the QCD pseudocritical temperature and curvature coefficient that validate the method as a reliable approach for probing the QCD crossover at small finite baryon density.
This paper develops a stochastic formulation of the Schwinger effect in de Sitter and generic FLRW spacetimes using the Schwinger-Keldysh formalism to describe particle production by non-stationary gauge backgrounds, establishing a framework applicable to early-Universe phenomena like inflation and preheating without relying on asymptotic out states.
Motivated by the recent LHC excess, this paper investigates whether a top-philic Type-III Two-Higgs-Doublet Model can simultaneously explain the anomaly and generate the observed baryon asymmetry of the Universe through electroweak baryogenesis, finding that while the model supports a strong first-order phase transition, only the explicit CP violation scenario remains viable within the current one-loop treatment compared to the transitional CP violation scenario.
