Elastic positivity from a modified forward dispersion relation constrains the twelve dim-8 Wilson coefficients of the photon–dark-photon EFT to a spectrahedral cone, with hierarchies for non-forward mixed amplitudes and distinct loci for kinetic-mixing and dark-axion UV completions.
Entanglement entropy in an acoustic black hole scales linearly with subregion volume due to long-range correlations from horizon phonon pair production and is approximated by the thermal entropy of Hawking radiation.
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.
The paper derives theoretical formulas relating positronium lifetime, 3γ/2γ annihilation rate ratio, and quantum entanglement degree to oxygen partial pressure, proposing them as novel PET-based hypoxia biomarkers.
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.
Point-cloud ML models classify charm- and bottom-origin electrons at ~80% purity for 40% efficiency, outperforming a BDT baseline, with performance limited by intrinsic decay similarity.
Visibility modulations from extra photon rings appear only for spherically symmetric boson stars near equatorial viewing angles; rotating models show incomplete crescent-shaped rings and no clean modulation.
Detector-aware merged targets for calorimeter showers improve GNN particle flow reconstruction performance and robustness to topology changes on independent samples.
A timing-based data-driven method to measure single-particle corner-clipping probabilities in segmented detectors, validated on Pierre Auger Underground Muon Detector simulations and parameterized by an analytical model.
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.
Ortho-leptonium states can be produced at significant rates through triphoton interactions in ultraperipheral Pb+Pb collisions at the LHC.
An upper bound on concurrence is derived for fixed local polarizations in two-qubit systems, saturated by pure states in some cases, and applied to show reduced maximal entanglement in polarized q qbar pairs from parity-violating Z decays.
Asymmetric Pati–Salam Z2 actions in free-fermionic heterotic orbifolds yield 24 inequivalent moduli classes and induce doublet–triplet splitting independent of moduli stabilisation.
Lyapunov exponents of charged probes capture the same cusp and transition points in dilatonic RN-AdS phase structure across Einstein and string frames, even though the exponent values themselves depend on frame for massive particles.
The Minkowski limit of pure R² gravity is reinterpreted as a thermal singularity via scalar-tensor to Eckart fluid analogy, showing infinite departure from GR rather than recovery.
Overlaps between Gaussian in-medium c-cbar wave functions and vacuum charmonium wave functions can reproduce LHC hadron ratios, implying in-medium pair sizes of about 0.85 fm (pp) and 0.55 fm (Pb-Pb compact part) and a mixed compact plus molecular X(3872).
Computes four-quark operator matrix elements via QCD sum rules, derives their HQET limit, demonstrates numerical consistency between the two, and identifies the source of prior literature discrepancies.
Black hole thermodynamic criticality exhibits universal relaxation scaling and critical slowing down determined by local bifurcation structures.
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.
