Including dimension-8 SMEFT operators alters the allowed parameter space for dimension-6 coefficients in fits to top-decay helicity fractions due to non-trivial correlations and degeneracies at O(Λ^{-4}).
The zeta(3)-proportional contribution to the four-loop twist-two gluon anomalous dimension gamma_gg^(3)(N) is constructed in analytic form from low-N moments via the LLL algorithm together with reciprocity and supersymmetric constraints.
Quantum entanglement degree of positronium photons is derived as a function of oxygen partial pressure using lifetime and 3γ/2γ ratio to enable new PET biomarkers for hypoxia.
Leading two-loop corrections to trilinear Higgs couplings in the 2HDM are calculated with focus on renormalization and di-Higgs phenomenology.
Exact analytic relations express M, α, D (and a) of Schwarzschild-MOG and Kerr-MOG black holes directly in terms of accretion-disk frequency shift, aperture angle, and redshift rapidity (plus acceleration in the rotating case).
Higher-order terms in an infinite tower of higher-derivative gravity regularize a 5D Proca-Maxwell system, creating frozen regular cores that mimic extremal black holes and satisfy all energy conditions.
An unfolded dynamics system for the on-shell hypermultiplet is built, from which harmonic, N=2, N=1 superspace and component formulations arise systematically, demonstrating background universality.
Leptophilic ALPs with m_a > f_a can explain the electron anomalous magnetic moment tension over a large parameter space and are testable via μ→e conversion.
Asymmetric orbifold actions in Pati-Salam heterotic strings yield 24 classes with 0-12 moduli, enabling exophobic three-generation models with moduli-independent doublet-triplet splitting.
Theoretical predictions show narrow peaks near DK and D*K thresholds in Ds pi and Ds* pi spectra plus large partial widths for isospin-violating decays of D1K and D2K molecular states.
A modified scotogenic model makes the lightest pseudo-Dirac singlet a dark matter candidate that annihilates mostly to neutrino pairs near threshold, reproducing the relic abundance while satisfying direct detection and lepton data bounds.
Numerical simulations show Shannon entropy and MIPP indicators distinguish chaotic from regular orbits of charged particles near weakly magnetized black holes in Einstein-ModMax theory, with parameters restricted by EHT shadow observations.
Generalized horizon entropy models satisfy BBN constraints on helium and deuterium abundances when parameters are chosen for cosmic acceleration, though lithium remains discrepant as in standard cosmology.
LHC vector boson fusion searches enhanced by machine learning can probe substantial regions of cosmologically viable parameter space for freeze-in dark matter mediated by a spin-2 particle.
In light-front holographic QCD the nucleon gravitational form factor B_N(t) vanishes exactly in the symmetric limit due to an antisymmetric longitudinal factor and remains strongly suppressed for realistic nucleon wave functions, explaining its observed smallness.
Fitting JUNO data with Lorentz invariance violation included moves the preferred neutrino mass ordering to inverted and sets new upper limits on CPT-even and CPT-odd LIV parameters.
Deviations from γ=1 in the Zipoy-Voorhees metric shift the (z,w,v) classification of periodic orbits and induce phase shifts plus amplitude modulations in their gravitational-wave signals.
Computes quasinormal modes and echoes for black bounce solutions, finding echoes only in certain symmetric horizonless cases and none in asymmetric models that recover Reissner-Nordström externally.
TransitionListener v2.0 supplies an end-to-end pipeline from scalar potential to gravitational wave spectra with improved handling of transition dynamics and bubble separation.
Generalizing entropy from e+e- annihilation with Tsallis statistics for pairs only leads to a 2σ bound of |q-1| ≤ 1.3×10^{-2} from CMB+BAO+BBN data.
The shadow of a Kerr-Newman-like black hole in Bumblebee gravity with plasma is analyzed via observables and constrained by M87* EHT data, with spin and Lorentz violation mainly distorting the shape while charge and plasma shrink the size.
Triphoton interactions in ultraperipheral Pb+Pb collisions produce observable ortho-leptonium and reproduce LHC data on J/ψ and dimuon production.
Dark matter halo parameters amplify the scale of closed timelike orbits in Schwarzschild spacetime, inducing phase lags in gravitational waves while light curves retain distinguishable peaks for certain orbital features.
