Neutrinoless double-beta decay of the $Δ^{-}$ resonance

Li-Ping He, Feng-Kun Guo, Ulf-G. Meißner +3

The subprocess $nn \to pp e^{-} e^{-}$ is a key ingredient in the interpretation of nuclear neutrinoless double-beta decay. Intermediate $Δ$ resonances may provide additional enhancements…

Dispersive analysis of the isospin breaking in the $X (3872) \to J / ψ π^{+} π^{-}$ and $X (3872) \to J / ψ π^{+} π^{0} π^{-}$ decays

Jorgivan Morais Dias, Teng Ji, Xiang-Kun Dong +5

We analyze the latest LHCb data on the $π^{+} π^{-}$ spectrum in the isospin-violating $X (3872) \to J / ψ π^{+} π^{-}$ decay, based on dispersion theory to deal with the $π π$ final state interac…
