The $D_{s 1} (2460)$ and other open-charm $1^{+}$ states in relativistic chiral effective field theory

Ze-Rui Liang, Qi-Chao Xiao, Zhi-Hui Guo +1

We derive the pertinent chiral potentials for charmed vector meson interactions with light pseudoscalar bosons in a relativistic U(3) chiral effective field theory up to next-to-le…

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…

Neutrinoless double beta decays of hyperons in covariant chiral perturbation theory

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

Neutrinoless double beta ( $0 ν β β$ ) decays of spin-1/2 hyperons are investigated in a covariant baryon chiral perturbation theory framework, extended by a $Δ L = 2$ operator proportiona…

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 $B_{1}^{-} \in {Σ^{-}, Ξ^{-}}$ and $B_{2}^{+} \in {p, Σ^{+}}$ , which violate lepton number…
