N and strangeness sigma terms at the physical point with chiral fermions
Yi-Bo Yang, Andrei Alexandru, Terrence Draper +2
Lattice QCD calculations with chiral fermions of the N sigma term and strangeness sigma term including chiral interpolation with continuum and volume correctio…
Strange and Charm Quark Spins from Anomalous Ward Identity
Ming Gong, Yi-Bo Yang, Jian Liang +3
We present a calculation of the strange and charm quark contributions to the nucleon spin from the anomalous Ward identity (AWI). It is performed with overlap valence quarks on 2+1…
Stochastic method with low mode substitution for nucleon isovector matrix elements
Yi-Bo Yang, Andrei Alexandru, Terrence Draper +2
We introduce a stochastic sandwich method with low-mode substitution to evaluate the connected three-point functions. The isovector matrix elements of the nucleon for the axial-vec…
Anatomy of the resonance from lattice QCD at the physical point
Wei Sun, Andrei Alexandru, Ying Chen +3
We propose a strategy to access the component of the resonance in lattice QCD. Through a mixed action formalism (overlap valence on domain wall sea), the energy of t…
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…
