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…

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…

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…
