This paper proposes a parasitic high-energy polarized gamma-ray facility at FCC-ee using Compton backscattering to achieve a four- to seven-fold improvement in precision for measuring the polarized gluon distribution in the medium- region through open-charm photoproduction.
This paper investigates resonant triple Higgs production within the Next-to-minimal Two Higgs Doublet Model (N2HDM), demonstrating that interference effects and additional decay channels significantly alter kinematic distributions and necessitate fully differential studies over simplified approximations to accurately probe extended Higgs sectors at the LHC.
This paper proposes a simple dissipative dark energy scenario that explains the recent DESI observations of an evolving dark energy component crossing the phantom divide without requiring pathological phantom-like dynamics.
This paper employs heavy meson effective field theory with effective spin-symmetry-breaking corrections to analyze excited charm-strange meson decays, successfully constraining mixing angles, validating a mixed assignment for the and states to resolve width discrepancies, and providing predictive decay patterns for higher-mass resonances.
This paper utilizes the SFitter global analysis framework within an effective quantum field theory approach to interpret current permanent electric dipole moment (EDM) measurements via a hadronic-scale Lagrangian, revealing that while some parameters are well-constrained, others require more high-precision data and that theory uncertainties can be managed within the analysis.
This paper extends the holographic V-QCD model by incorporating a charged scalar field to describe quark pairing, revealing a phase diagram with a second-order transition to color superconductivity at temperatures up to ~30 MeV, though the formation of homogeneous paired phases is found to be subdominant to previously discovered modulated phases.
This paper derives next-to-leading order chiral perturbation theory expressions for QCD-like theories with non-degenerate fermion masses, applies them to extract low-energy constants from lattice data, and demonstrates the critical role of these corrections in refining the viable parameter space for pion dark matter scenarios.
This paper updates the spectrum of heavy hybrid mesons in the charmonium and bottomonium sectors using the Born-Oppenheimer Effective Field Theory framework and recent lattice QCD data to analyze their transitions to conventional quarkonia, ultimately providing interpretations for observed XYZ states and identifying new hybrid candidates.
This paper proposes a ferromagnet lattice magnetometer that coherently combines multiple levitated ferromagnets to significantly enhance sensitivity for detecting ultralight dark matter by suppressing dipole-dipole interactions and leveraging collective readout, thereby surpassing existing single-ferromagnet constraints across various coupling models.
This paper argues that hybrid stars are unlikely candidates for observed mass-gap compact objects because Bayesian analysis of modern mass-radius constraints favors equations of state with deconfinement occurring around , which would produce twin stars that effectively rule out hybrid stars in the mass gap.
