Connected and Disconnected Sea Partons from CT18 Parametrization of PDFs
Tie-Jiun Hou, Mengshi Yan, Jian Liang +2
The separation of the connected and disconnected sea partons, which were uncovered in the Euclidean path-integral formulation of the hadronic tensor, is accommodated with an altern…
Connected and Disconnected Sea Partons from CT18 Parametrization of PDFs
Tie-Jiun Hou, Jian Liang, Keh-Fei Liu +2
The separation of the connected and disconnected sea partons, which were uncovered in the Euclidean path-integral formulation of the hadronic tensor, is accommodated with the CT18…
Parton distributions and lattice QCD calculations: toward 3D structure
Martha Constantinou, Aurore Courtoy, Markus A. Ebert +24
The strong force which binds hadrons is described by the theory of Quantum Chromodynamics (QCD). Determining the character and manifestations of QCD is one of the most important an…
Lattice Calculation of Pion Form Factor with Overlap Fermions
Gen Wang, Jian Liang, Terrence Draper +2
We present a precise calculation of the pion form factor using overlap fermions on seven ensembles of 2+1-flavor domain-wall configurations with pion masses varying from 139 to 340…
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…
Towards the nucleon hadronic tensor from lattice QCD
Jian Liang, Terrence Draper, Keh-Fei Liu +2
We present the first calculation of the hadronic tensor on the lattice for the nucleon. The hadronic tensor can be used to extract the structure functions in deep inelastic scatter…
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 spins and Anomalous Ward Identity
Jian Liang, Yi-Bo Yang, Terrence Draper +2
We calculate the intrinsic quark spin contribution to the total proton spin using overlap valence quarks on three ensembles of -flavor RBC/UKQCD domain-wall configurations wit…
Strange Quark Magnetic Moment of the Nucleon at Physical Point
Raza Sabbir Sufian, Yi-Bo Yang, Andrei Alexandru +3
We report a lattice QCD calculation of the strange quark contribution to the nucleon's magnetic moment and charge radius. This analysis presents the first direct determination of s…
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…
