This paper demonstrates that reconstructing spin density matrices via quantum tomography and analyzing quantum information-inspired observables for near-threshold top-antitop production at the LHC significantly enhances the sensitivity to detect subtle toponium formation effects.
This paper proposes using the super-binomial variance in atom interferometer count rates as a highly sensitive new signature for detecting dark matter, offering orders-of-magnitude enhanced sensitivity over independent-atom estimates and providing complementary constraints on dark matter interactions with standard model particles.
This paper systematically evaluates hadronic contributions to the muon within improved holographic QCD models, revealing that while the frameworks reproduce low-energy spectra, they underestimate the hadronic vacuum polarization due to a deficient -meson decay constant and exhibit significant variations in the hadronic light-by-light contribution driven by differences in the pion transition form factor at low momentum transfer.
This paper presents a finite-temperature lattice study of Sp(4) Yang-Mills theory using the Logarithmic Linear Relaxation algorithm to characterize its first-order confinement/deconfinement phase transition, estimate discretization and finite-volume artifacts, and establish bounds for the continuum theory's critical coupling, specific heat, and surface tension.
This paper employs cluster effective field theory, fitted to recent experimental data from the LUNA and JUNA collaborations, to calculate the factor of the C(,)O reaction at low energies and extrapolate it to the Gamow peak relevant for low-mass AGB stars, identifying the near-breakup threshold state of O as the primary source of uncertainty.
This paper investigates how anomalous magnetic and electric dipole moments of the tau lepton influence its polarization and spin correlations in pair production processes at the LHC and future colliders, utilizing the TauSpinner Monte Carlo program to present observable signatures of these potential New Physics effects.
This paper proposes that dark radiation-matter decoupling resolves the Hubble tension by predicting dark acoustic oscillations with specific scales and amplitudes that align with recent DESI anomalies, offering a viable alternative to evolving dark energy models.
This paper presents the NNPDF collaboration's perspective on the current status and challenges of determining Parton Distribution Functions, emphasizing their critical role in extracting fundamental Standard Model parameters and Beyond the SM Wilson coefficients through both stand-alone and joint analyses.
This paper presents a systematic QCD sum-rule analysis of charged kaons in hot and dense matter, deriving their in-medium masses and decay constants to reveal a significant mass splitting driven by baryonic interactions and identifying a critical density threshold that signals the onset of chiral symmetry restoration.
This paper proposes a class of models based on a gauged flavor symmetry that simultaneously explains the fermion mass hierarchy via the Froggatt-Nielsen mechanism and solves the strong CP problem with a high-quality axion, while also providing a unified framework for dark matter, leptogenesis, and testable flavor-changing predictions.
