This review presents a bottom-up theoretical framework for electric dipole moments (EDMs) that traces the connection from fundamental CP-violating interactions at the quark-gluon level to observable EDMs in nucleons, nuclei, atoms, and molecules, emphasizing the role of chiral perturbation theory and the complementarity of various systems in identifying the sources of CP violation beyond the Standard Model.
This paper presents a theoretical one-zone leptonic model incorporating stochastic turbulent acceleration and nonlinear synchrotron self-Compton cooling to explain diverse X-ray interband time lags in high-frequency-peaked BL Lac objects, demonstrating how the competition between acceleration, cooling, and escape processes creates distinct lag regimes and a unifying framework for interpreting observed flare signatures.
This paper establishes a model-independent framework connecting low-frequency scalar-induced gravitational waves and high-frequency primordial black hole merger signals, demonstrating that their shared origin in enhanced curvature perturbations allows for a unified probe of early-universe physics across widely separated frequency bands.
This paper refines the sensitivity estimates for Single-Molecule Magnet dark matter detectors by deriving a new analytic model that accounts for stochastic spin relaxation to lower the energy threshold for avalanche formation, supported by simulations and experimental verification of the thermal properties of Mn-acetate and Mn crystals.
This paper demonstrates that hyperons in core-collapse supernovae reach local chemical equilibrium rapidly via nonleptonic reactions and significantly enhance muon (anti)neutrino opacities through semileptonic channels, thereby influencing proto-neutron star evolution and flavor-dependent neutrino transport.
This paper presents a comprehensive analysis of exclusive semileptonic decays within and beyond the Standard Model by employing Heavy Quark Effective Theory with a data-driven -expansion to predict precise lepton flavor universality ratios and evaluate the sensitivity of various observables to new physics scenarios, including the Two Higgs Doublet Model and effective field theories.
This paper presents a reduced-profile maximum-entropy method that constructs constrained zero-skewness valence-quark generalized parton distribution transverse profiles by integrating nucleon electromagnetic form factors and forward parton distribution functions to establish a stable baseline for analyzing impact-parameter distributions.
This paper introduces a novel, adaptive numerical method for solving canonical differential equations of Feynman integrals using Chebyshev polynomial approximations, which offers competitive efficiency and robust stability across physical phase space with minimal manual intervention for singularities.
This study investigates the reaction to identify low-lying states, confirming the and while finding that the necessity of the predicted state depends on whether interactions are included in the analysis.
This paper presents a precision study of low-scale cosmological phase transitions in a dark Abelian Higgs sector using dimensionally reduced effective field theory, finding that while higher-order thermal corrections significantly alter predictions, the parameter region favored by current pulsar timing array data lies near the theory's validity boundary and remains disfavored by observations, while also identifying asymmetric freeze-out as a viable dark matter mechanism.
