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 $N_f=2+…
Nucleon mass in covariant baryon chiral perturbation theory at leading two-loop order
Ze-Rui Liang, Han-Xue Chen, Feng-Kun Guo +2
We calculate the nucleon mass within a manifestly relativistic formulation of baryon chiral perturbation theory (BChPT), extending the framework to leading two-loop order ($\mathca…
ChPT and lattice QCD studies of doubly charmed baryons
Ze-Rui Liang, Jing-Yu Yi, Liuming Liu +1
The scattering lengths on the interactions between the spin- doubly charmed baryons and Nambu-Goldstone bosons are of great importance for the investigation of the spectroscop…
Chiral Representation of the Nucleon Mass at Leading Two-loop Order
Ze-Rui Liang, Han-Xue Chen, Feng-Kun Guo +2
We calculate the nucleon mass in a manifestly relativistic baryon chiral perturbation theory up to the leading two-loop order. Through dimensional counting analysis, we perform the…
Low-energy elastic (anti)neutrino-nucleon scattering in covariant baryon chiral perturbation theory
Jin-Man Chen, Ze-Rui Liang, De-Liang Yao
The low-energy antineutrino- and neutrino-nucleon neutral current elastic scattering is studied within the framework of the relativistic SU(2) baryon chiral perturbation theory up…
