The and other open-charm 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 resonance
Li-Ping He, Feng-Kun Guo, Ulf-G. MeiÃner +3
The subprocess is a key ingredient in the interpretation of nuclear neutrinoless double-beta decay. Intermediate resonances may provide additional enhancement…
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…
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 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, with and , which violate lepton numb…
Gravitational form factors of pions, kaons and nucleons from dispersion relations
Xiong-Hui Cao, Feng-Kun Guo, Qu-Zhi Li +2
The gravitational form factors of pions, kaons and the nucleons are investigated by employing modern dispersive techniques and chiral perturbation theory. We determine the gravitat…
