Reformulating local polynomial fitting with orthogonal Chebyshev polynomials yields two algorithms that cut memory use, improve scalability, and deliver orders-of-magnitude better numerical accuracy than Vandermonde-based methods for Savitzky-Golay filters.
No excess observed; first LHC search sets 95% CL upper limits on H to AA to 4e branching fraction down to 10^{-5} for 10-100 MeV masses and short lifetimes.
Path integral quantization of topologically coupled massive p-form theories shows quantum duality breaking on non-trivial backgrounds, with the difference in required counterterms proportional to the Euler characteristic.
A piezoelectric-driven glass capillary launcher enables localized, high-efficiency (up to 93%) in-vacuum loading of silica spheres, nanodiamonds, and plate-like particles into single-beam, dual-beam, and standing-wave optical traps.
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.
Extended misalignment for axion-like particles with constant-ω_ϕ pre-oscillation and dark radiation coupling yields data-driven constraints favoring negative ω_ϕ and f_ϕ in [80, 1.5×10^10] TeV but does not ease cosmological tensions.
De Sitter entropy is carried by hairons from S^4/Z_N instantons, yielding a 1/N information see-saw for neutrino masses with N ~ 10^120.
A reweighting method creates model-agnostic likelihoods from histogram analyses, applied to Belle II B+ to K+ nu nubar data for WET constraints and light new physics searches.
Axion-photon oscillations generate bipartite mode entanglement with maximal values at resonance, and quantum speed limits are derived for both axion-photon and neutrino systems.
Quantum gravity forces the QCD theta parameter to emerge as the vev of a local axion field through coherent-state representations of geometry and a quantum-information interpretation of topological-charge superselection.
No photon-ALP conversion signal found in HAWC data from M87, producing competitive constraints excluding ALP masses of 10^{-8} to 10^{-6} eV for couplings above 5×10^{-12} GeV^{-1}.
Computation of axion-mediated parity-violating electron-electron interaction in the RaOCH3 symmetric top molecule using generalized relativistic effective core potentials and one-center restoration, averaged over lowest rovibrational states.
Natural SUSY with axino LSP allows viable mixed axion-axino dark matter matching the observed abundance for axino masses near 100 keV and PQ scales of 10^11 to 3x10^12 GeV in DFSZ and KSVZ models.
Radioactive molecules combine nuclear and molecular properties to offer enhanced sensitivity for detecting new physics beyond the Standard Model.
CUPID-0 achieves 39.8 ± 2.1 keV FWHM resolution at 5.5 MeV for single-crystal events, enabling low-background axion searches.
An integrated experimental system for sub-eV ALP searches using four-wave mixing has been commissioned and validated at ELI-NP with 20 mJ laser pulses at 1.3e-7 mbar vacuum.
