This study systematically investigates the meson-baryon molecular nature of hidden charm pentaquark states and using a coupled-channel framework with heavy quark spin symmetry, revealing that while full symmetry treatment is essential for the system, the system yields similar results with simplified sector splitting, and confirming that the resulting bound states possess characteristic molecular radii between 0.5 and 2 fm.
This paper presents a comprehensive Bayesian MCMC analysis of the meson spectrum using standard and logarithmically modified Cornell potentials to rigorously quantify uncertainties, probe the sensitivity of excited states to confinement forms, and provide updated theoretical predictions for future experimental benchmarks.
This paper proposes a Type I seesaw model with symmetry and soft-breaking terms at the electroweak scale that successfully explains light neutrino oscillation data, identifies the lightest right-handed neutrino as a dark matter candidate via freeze-in, and generates the baryon asymmetry through resonant leptogenesis using only a minimal set of parameters.
This paper derives updated supernova constraints on muon-philic scalars and pseudoscalars by incorporating two-photon couplings from muon triangle loops, revealing that while globular-cluster limits dominate for light masses, supernova 1987A gamma-ray observations and energy-loss arguments impose stringent bounds on heavier masses that challenge the viability of these bosons explaining the muon magnetic-moment anomaly.
This paper demonstrates that in axion monodromy inflation, oscillatory modulations of the potential continuously excite heavy moduli fields, thereby invalidating the conventional single-field approximation and generating detectable cosmological collider signals in the primordial bispectrum that bypass standard Boltzmann suppression.
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.
