Roper State from Overlap Fermions
Mingyang Sun, Ying Chen, Gen Wang +11
The Roper state is extracted with valence overlap fermions on a -flavor domain-wall fermion lattice (spacing fm and MeV) using both the Sequential Empi…
Ratio of strange to momentum fraction in disconnected insertions
Jian Liang, Mingyang Sun, Yi-Bo Yang +2
The ratio of the strange quark momentum fraction to that of light quark or in disconnected insertions (DI) is calculated on the lattice with…
Quark Spin in Proton from Anomalous Ward Indentity
Yi-Bo Yang, Ming Gong, Keh-Fei Liu +1
We report a quark spin calculation from the anomalous Ward identity with overlap fermions on 2+1 flavor dynamical fermion configurations with light sea quark masses. Such a formula…
Strange quark momentum fraction from overlap fermion
Mingyang Sun, Yi-Bo Yang, Keh-Fei Liu +1
We present a calculation of for the strange quark in the nucleon. We also report the ratio of the strange to that of in the disconnected insertion which wil…
Glue Spin in The Longitudinally Polarized Nucleon
Raza Sabbir Sufian, Michael J. Glatzmaier, Yi-Bo Yang +2
We present a lattice QCD calculation of the glue spin in the nucleon for the first time. It was recently shown that the first moment of the glue helicity distribution could b…
The Roper Puzzle
Keh-Fei Liu, Ying Chen, Ming Gong +3
We carried out a calculation of the Roper state with the Sequential Empirical Bayesian (SEB) method with overlap valence fermion on 2+1-flavor domain-wall fermion configurations on…
