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

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

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

Production of $J / I ¨ p p ˉ$ in electron-positron collisions

Xiao-Yu Zhang, Yi-Lin Song, Feng-Kun Guo

The discoveries of the hidden-charm $P_{c}$ pentaquarks by the LHCb Collaboration have been not confirmed by other experiments yet. It is desirable to investigate the feasibility of…

Production of $1^{-+}$ exotic charmonium-like states in electron-positron collisions

Xiao-Yu Zhang, Pan-Pan Shi, Feng-Kun Guo

The absence of observed charmonium-like states with the exotic quantum numbers $J^{P C} = 1^{-+}$ has prompted us to investigate the production rates of the $1^{-+}$ $D D ˉ_{1} (2420)$ …
