The 1-loop correction of the QCD energy momentum tensor with the overlap fermion and HYP smeared Iwasaki gluon
Yi-Bo Yang, Michael Glatzmaier, Keh-Fei Liu +1
We present the 1-loop renormalization of the energy momentum tensor using the overlap fermion and a HYP-smeared Iwasaki gauge action. We also calculate the 1-loop matching coeffici…
Glue spin and helicity in proton from lattice QCD
Yi-Bo Yang, Raza Sabbir Sufian, Andrei Alexandru +4
We report the first lattice QCD calculation of the glue spin in the nucleon. The lattice calculation is carried out with valence overlap fermions on 2+1 flavor DWF gauge configurat…
Glue Spin of the Proton
Yi-Bo Yang, Raza Sabbir Sufian, Andrei Alexandru +3
We report the progress on the lattice QCD calculation of the glue spin contribution to proton spin. This calculation is carried out with valence overlap fermion on 2+1 flavor DWF g…
Unphysical Poles of Domain Wall Fermions at finite
Raza Sabbir Sufian, Michael J. Glatzmaier, Yi-Bo Yang
We investigate the origin and behavior of oscillations observed in the hadron correlators constructed from the domain wall fermion (DWF) for different parameters involved in lattic…
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…
Perturbative Renormalization and Mixing of Quark and Glue Energy-Momentum Tensors on the Lattice
Michael Glatzmaier, Keh-Fei Liu, Yibo Yang
We report the renormalization and mixing constants to one-loop order for the quark and gluon energy-momentum (EM) tensor operators on the lattice. A unique aspect of this mixing ca…
Non-perturbative renormalization of overlap quark bilinears on domain wall fermion configurations
Zhaofeng Liu, Ying Chen, Yi-Bo Yang +6
We present renormalization constants of overlap quark bilinear operators on 2+1-flavor domain wall fermion configurations. Both overlap and domain wall fermions have chiral symmetr…
Non-perturbative renormalization of overlap quark bilinears on 2+1-flavor domain wall fermion configurations
Zhaofeng Liu, Ying Chen, Shao-Jing Dong +6
We present renormalization constants of overlap quark bilinear operators on 2+1-flavor domain wall fermion configurations. This setup is being used by the chiQCD collaboration in c…
A Lattice Study of Quark and Glue Momenta and Angular Momenta in the Nucleon
M. Deka, T. Doi, Y. B. Yang +10
We report a complete calculation of the quark and glue momenta and angular momenta in the proton. These include the quark contributions from both the connected and disconnected ins…
Strangeness and charmness content of nucleon from overlap fermions on 2+1-flavor domain-wall fermion configurations
M. Gong, A. Alexandru, Y. Chen +8
We present a calculation of the strangeness and charmness contents <N|\bar{s}s|N> and <N|\bar{c}c|N> of the nucleon from dynamical lattice QCD with 2+1 flavors. The calculation is…
Higher Twist in Electroproduction: Flavor Non-Singlet QCD Evolution
Michael J. Glatzmaier, Sonny Mantry, Michael J. Ramsey-Musolf
We present results for the one loop anomalous dimension matrix of flavor non-singlet twist-4 operators of lowest spin that contribute to the leading moment of the structure f…
