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…

Low-energy interactions between doubly charmed baryons and Goldstone bosons from lattice QCD

Jing-Yu Yi, Ze-Rui Liang, Liuming Liu +1

We perform a lattice QCD calculation of the $S$ -wave interactions between the ground-state spin- $1/2$ doubly charmed baryons and Goldstone bosons. The lattice QCD simulations are c…

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…

A lattice QCD study of low-energy interactions of doubly charmed baryons

Jing-Yu Yi, Ze-Rui Liang, Liuming Liu +1

We present a lattice QCD calculation of the S-wave interactions between the spin-1/2 doubly charmed baryons ( $I^_{cc}, I^c ◯_{cc}$ ) and Goldstone bosons ( $I ¨ , K, K ˉ$ ) using the $N_f…

Two-Loop Extraction of the Pion-Nucleon Sigma Term

Ze-Rui Liang, Han-Xue Chen, Feng-Kun Guo +2

The pion-nucleon sigma term, characterizing the mass component of Higgs origin related to $u$ and $d$ quarks inside the nucleon, is investigated within relativistic baryon chiral p…
