This paper demonstrates that incorporating higher-order curvature corrections (such as and ) into the Starobinsky inflationary model resolves its mild tension with recent P-ACT-LB-BK18 data while imposing new constraints on post-inflationary dynamics.
This paper introduces a novel amortized inference technique using likelihood-weighted Normalizing Flows that overcomes the limitations of standard unimodal base distributions in capturing multi-modal posteriors by initializing the flow with a Gaussian Mixture Model, thereby enabling efficient and accurate parameter estimation in high-dimensional inverse problems without requiring posterior training samples.
This paper demonstrates that a lightweight and scalable EfficientNet architecture, augmented with global jet features, achieves competitive top-quark jet tagging performance while significantly reducing computational costs compared to Transformer-based and standard Graph Neural Network approaches.
This paper presents a generalized framework for calculating nonperturbative effects in minimal dark matter models, demonstrating that while individual multiplet scenarios are testable by next-generation direct-detection experiments, specific mixed Majorana-Dirac multiplet combinations can evade these limits by producing signals below the neutrino floor, thereby necessitating complementary detection methods for a complete test of the theory.
This paper presents the first next-to-next-to-leading order calculation of the four-jet production rate in electron-positron annihilation, utilizing advanced antenna subtraction and new transcendental functions to achieve improved agreement with LEP data and significantly reduced theoretical uncertainties.
This paper demonstrates that incorporating two-loop corrections and approximate heavy quark mass effects into the perturbative splitting kernels significantly improves the quantitative accuracy and predictive stability of double parton distributions at small inter-parton distances.
This paper employs renormalizable two- and three-flavor quark-meson-diquark models to analyze color superconductivity and pion condensation in dense quark matter, demonstrating that BCS gaps approach a constant and the speed of sound converges to the conformal limit at high chemical potentials while correctly accounting for global symmetry breaking and Goldstone boson counting.
This study investigates temperature-dependent dark matter-neutrino interactions induced by a dimension-six operator, deriving a full Boltzmann hierarchy that reveals dark acoustic oscillations and establishes significantly tighter cosmological constraints on the interaction strength compared to temperature-independent models, while highlighting the critical impact of realistic neutrino mass ordering on these limits.
This paper demonstrates that a significantly enhanced isovector nuclear spin-orbit interaction, inferred from CREX experimental data on Ca, resolves the PREX-CREX puzzle and explains the emergence of new magic numbers in neutron-rich nuclei while preserving the successful description of standard nuclear properties.
This study employs a Bayesian approach to generate hybrid star equations of state combining hadronic and quark matter models, demonstrating that vector and multiquark interactions are essential for supporting massive neutron stars consistent with NICER and pQCD constraints while predicting a positive trace anomaly in their cores.
