This paper derives a basis-independent, rephasing-invariant expression for the Dirac CP phase under specific approximations of charged lepton mixing and establishes a method to reduce unitarity constraints for arbitrary unitary matrices, thereby enabling the direct translation of theoretical results from the PDG parametrization into rephasing invariants.
This paper presents a physics-informed neural network approach to extract a universal small- dipole scattering amplitude directly from global DIS and photoproduction data without rigid parametric assumptions, successfully resolving the long-standing tension between total and charm cross-section channels while providing a smooth, non-negative input for Color Glass Condensate phenomenology.
This paper offers a pedagogical review of the Schwinger effect, tracing its origins in quantum electrodynamics and exploring its extensions to quantum chromodynamics and applications in nuclear physics, such as string breaking, high-Z nuclei, relativistic heavy-ion collisions, and the chiral anomaly.
This paper demonstrates that within a nonlocal NJL model, a sufficiently large chiral chemical potential can enable the QCD-biased axionic domain-wall scenario to explain the NANOGrav 15-year gravitational wave data even at large angles, where the topological susceptibility exhibits a pronounced width near the critical temperature.
This paper proposes an extended left-right symmetric model incorporating an additional gauge symmetry and vector-like fermions to explain neutrino mass hierarchies through distinct seesaw mechanisms, while utilizing LHC Run II data to establish lower mass limits on the new and gauge bosons based on their decay channels.
This paper demonstrates that in the two-Higgs-doublet model, the non-conformal realization with explicit mass terms produces significantly stronger first-order electroweak phase transitions and potentially observable gravitational wave signals compared to the classically conformal version, which is restricted to weaker transitions unless the scalon is light.
This paper theoretically establishes that the anomalous magnetic moment of a photon increases with strong magnetic fields up to $30\, B_{\rm cr}$, linking this behavior to vacuum birefringence and providing precise predictions for ellipticity and polarization observables to guide future experimental verification.
This paper extends a single-flavon -lattice Froggatt-Nielsen framework to the lepton sector, successfully generating charged-lepton mass hierarchies and a normal-ordered neutrino spectrum while predicting a distinct two-branch correlation between the atmospheric mixing angle and the CP-violating phase , with a lower-octant solution (, ) favored by theoretical priors.
This paper utilizes anticipated JUNO results on solar neutrino oscillation parameters to establish updated conditions under which the effective Majorana mass in the normal ordering scenario is guaranteed to exceed specific meV thresholds, considering both generic and symmetry-constrained Majorana phase scenarios.
This paper utilizes Heavy Quark Effective Theory (HQET) within weakly coupled gauge theories to derive the classical Frank-Tamm formula for Cherenkov radiation and simultaneously calculate the leading-order thermal and quantum fluctuations around this spectrum.
This paper introduces alternative classical relativistic Lagrangians for point-particle analogs of the Standard-Model Extension that possess well-defined massless limits, enabling the description of Lorentz-violating photons through Dirac constraint techniques with potential applications in gravitational fields and Finsler geometry.
This paper demonstrates that the energy levels of QED bound states, such as muonic hydrogen, can be calculated using matrix elements of the energy-momentum tensor trace, showing analytically and diagrammatically how this method yields results consistent with standard one-loop Lamb shift calculations despite employing different diagrammatic sets.
This presentation reviews potential Lorentz violation signals in atomic and molecular spectroscopy by summarizing current constraints on nonrelativistic SME coefficients, outlining prospects for first-time bounds on unconstrained parameters, and emphasizing the critical role of high-angular-momentum states in these symmetry tests.
This paper argues that in interacting quantum field theories at finite density, the derivative of entanglement entropy with respect to subregion size converges to the thermal entropy density in the large-subregion limit, thereby establishing a universal link between entanglement and thermodynamics that allows for the extraction of equation-of-state information, as demonstrated nonperturbatively in the three-dimensional O(4) model.
This paper develops a machine learning-based analytical emulator to model the baryon density distribution within fuzzy dark matter solitons, successfully reproducing empirical profiles with high accuracy and offering a viable alternative to explicit equations of motion for studying soliton formation and evolution.
This study analyzes the covariance spectrum of the black hole X-ray binary MAXI J1820+070 up to 150 keV, revealing a high-energy coherence drop and distinct electron temperature behaviors that support a two-Comptonization model where short-timescale variability originates from an elevated inner region illuminated by cooler disk photons, while long-timescale variability arises from larger radii.
This review outlines the fundamental theory and numerical methods for modeling the coupled magnetic and thermal evolution of isolated neutron stars, providing benchmark tests and discussing recent advancements from axisymmetric to fully three-dimensional simulations to explain their diverse observational properties.
This paper investigates how dark dipole radiation from eccentric supermassive black hole binaries can accelerate their inspiral and alter the low-frequency stochastic gravitational-wave background, finding that while it cannot fully resolve the final-parsec problem, it remains detectable through Bayesian analysis of current pulsar timing array data.
This paper extends the concept of "dark moment" couplings to the Standard Model W boson within a specific portal matter model, demonstrating that while direct W boson interactions with dark photons remain difficult to detect at the LHC due to small rates and large backgrounds, the direct production of the underlying portal matter scalars offers a more promising discovery channel already constrained by existing searches.
This paper computes all planar three-loop master integrals required for leading-colour N3LO QCD corrections to the production of two massive or off-shell vector bosons at hadron colliders by constructing pure integral bases, deriving canonical differential equations via finite field techniques, and solving them using generalised power series expansions.
