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…

Neutrinoless double beta decays of hyperons in covariant chiral perturbation theory

Zi-Ying Zhao, Ze-Rui Liang, Feng-Kun Guo +2

Neutrinoless double beta ( $0 I^½ I^^{2} I^^{2}$ ) decays of spin-1/2 hyperons are investigated in a covariant baryon chiral perturbation theory framework, extended by a $I^ L = 2$ operator proport…

Hyperon neutrinoless double beta decays in chiral perturbation theory

Zi-Ying Zhao, Ze-Rui Liang, Feng-Kun Guo +2

We study the neutrinoless double beta decays of spin-1/2 hyperons, $B_{1}^{-} \to B_{2}^{+} ℓ^{-} ℓ^{-}$ with $B_{1}^{-} \in {I^£^{-}, I^^{-}}$ and $B_{2}^{+} \in {p, I^£^{+}}$ , which violate lepton numb…
