Using an effective Lagrangian approach and SU(3) flavor symmetry, this study investigates the production and decay of molecular states composed of and , predicting sizable branching ratios from meson decays ( and , respectively) and narrow decay widths on the order of MeV.
This paper proposes a novel framework where a spontaneously broken global symmetry generates a residual symmetry that stabilizes dark matter while suppressing proton decay to the one-loop level, thereby linking the proton lifetime to dark matter mass and predicting distinctive TeV-scale leptoquark signatures accessible to current and future experiments.
This study experimentally confirms that the late-time fluorescence decay of Acridine Orange follows a two-exponential law with lifetimes of approximately 1.73 ns and 5.95 ns, finding no evidence for the predicted power-law deviation while validating the experimental setup for precise lifetime determination.
This paper proposes that pulsar polarimetry, when cross-correlated with timing data, can detect parity-violating circular polarization in nanohertz stochastic gravitational wave backgrounds by inducing a measurable rotation in pulsar polarization signals that shares the characteristic Hellings-Downs angular pattern.
This paper extends the Kuhn-Mirkes formalism for semileptonic tau decays to include contributions from potential tensor interactions beyond the Standard Model, emphasizing the necessity of measuring generalized spectral functions for model-independent studies of CP and T violation in multi-meson final states.
This paper employs supervised machine learning to evaluate the distinguishability of four neutron star matter models using macroscopic and oscillation-related quantities, revealing that while certain scenarios can be separated under controlled assumptions, others exhibit intrinsic degeneracies due to fundamental similarities in their effective equations of state.
This paper proposes that the behavior of the effective potential in Higgs-portal scalar singlet systems, characterized by a topologically stable non-simple singularity with Milnor number , can be comprehensively mapped and experimentally verified through high-precision measurements of Higgs couplings and gravitational waves, ensuring that any viable strong first-order electroweak phase transition will be detected or ruled out by 2040.
This paper presents a five-dimensional holographic construction of the QCD axion that clarifies its relationship with the meson and anomalies, while demonstrating that solving the axion quality problem requires significant axion compositeness and a physical state predominantly residing in the bulk gauge field.
This paper proposes a novel mechanism where a large matter-antimatter asymmetry in Dirac fermions generates finite-temperature radiative corrections that destabilize cosmological domain walls, offering a unique pathway to probe the asymmetry's magnitude and generation temperature through future gravitational wave observations while potentially explaining baryon asymmetry, dark matter, and neutrino asymmetry.
This paper investigates how Planck-scale quantum-gravity corrections, modeled via a dimension-5 operator in a (3+1) four-flavor neutrino framework, induce significant deviations in the atmospheric mixing angle and alter the entanglement entropy evolution of neutrino oscillations, thereby offering a sensitive probe for Planck-scale physics.
