This paper presents the first constraints on the axion-photon coupling () using soft X-ray observations of the quiet Sun from India's Chandrayaan-2 mission, establishing an upper limit of approximately GeV at 95% confidence for axion masses below eV.
This paper demonstrates that core-collapsed self-interacting dark matter halos of approximately provide a unified explanation for three distinct astrophysical observations: the dense perturber affecting the GD-1 stellar stream, the structural properties of a perturber in the JVAS B1938+666 strong lensing system, and the origin of the Fornax 6 stellar cluster.
This paper presents the first lattice QCD determination of the electromagnetic form factors for the tetraquark, revealing its internal structure as a compact bound state of a heavy diquark and a light antidiquark with a charge radius significantly smaller than that of the threshold.
This paper demonstrates that the Next-to-Two-Higgs-Doublet Model (N2HDM) can simultaneously explain the LHC and LEP anomalies at 95 GeV and the 650 GeV excess by predicting a heavy CP-even Higgs boson decaying into a 125 GeV Higgs and a 95 GeV scalar, a scenario consistent with current experimental constraints and offering distinct testable signatures for future collider runs.
Using three-point QCD sum rules with vacuum condensates up to dimension 5, this study investigates the strong decays of four vector tetraquark candidates for the and finds that the predicted total width of for the configuration () aligns excellently with experimental data, thereby supporting this specific tetraquark interpretation.
This paper employs QCD sum rules to construct color five-quark currents and calculate the mass spectrum of hidden-charm doubly-strange pentaquark states with specific quantum numbers, providing theoretical predictions for future experimental searches in decays while challenging the conventional "good" and "bad" diquark classification.
This paper derives a comprehensive and compact spin density matrix for octet baryon-antibaryon pairs produced in polarized electron-positron annihilation within the one-photon-exchange approximation, explicitly incorporating parity and CP violation effects alongside finite electron mass corrections to facilitate the study of angular distributions and quantum entanglement.
This paper demonstrates that the mass spectra of both mesons and baryons are accurately described by a parameter-free open-string model with a consistent Hagedorn temperature of approximately 0.34 GeV, supporting the view of baryons as quark-diquark systems and offering new insights into quark deconfinement.
This paper proposes a hybrid nuclear-electronic spin sensor utilizing hyperfine interactions in silicon donors to overcome the low-frequency sensitivity limits of conventional nuclear magnetic resonance, thereby enabling compact solid-state detection of galactic axions with projected sensitivity exceeding direct nuclear methods by an order of magnitude.
This paper presents a comprehensive calculation of two-, three-, and four-body Higgs decay rates at next-to-leading order in both QCD and electroweak interactions within the dimension-6 SMEFT framework, implemented in the publicly available Monte Carlo program NEWiSH to assess the impact of these corrections on future collider projections.
