Neutrinoless double-beta decay of the resonance
Li-Ping He, Feng-Kun Guo, Ulf-G. Meißner +3
The subprocess is a key ingredient in the interpretation of nuclear neutrinoless double-beta decay. Intermediate 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 () decays of spin-1/2 hyperons are investigated in a covariant baryon chiral perturbation theory framework, extended by a 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, with and , which violate lepton number…
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 -wave interactions between the ground-state spin- doubly charmed baryons and Goldstone bosons. The lattice QCD simulations are c…
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 () and Goldstone bosons () using the $N_f=2+…
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 and quarks inside the nucleon, is investigated within relativistic baryon chiral p…
