Moments of Nucleon Light Cone Quark Distributions Calculated in Full Lattice QCD
Moments of the quark density, helicity, and transversity distributions are calculated in unquenched lattice QCD. Calculations of proton matrix elements of operators corresponding to these moments
Lattice Perturbation Theory
Mellin moments ⟨x⟩ and ⟨x2⟩ for the pion and kaon from lattice QCD
We present a calculation of the pion quark momentum fraction, $⟨x⟩$, and its third Mellin moment $⟨{x}^{2}⟩$. We also obtain directly, for the first time, $⟨x⟩$ and $⟨{x}^{2}⟩$ for the kaon using
One-loop matching for parton distributions: Nonsinglet case
We derive the one-loop matching condition for nonsinglet quark distributions in the transverse-momentum cutoff scheme, including unpolarized, helicity and transversity distributions. The matching is
The Mellin moments $\langle x \rangle$ and $\langle x^2 \rangle$ for the pion and kaon from lattice QCD
We present a calculation of the pion quark momentum fraction, $\langle x \rangle$, and its third Mellin moment $\langle x^2 \rangle$. We also obtain, for the first time, $\langle x \rangle$ and

Perturbative renormalization of weak Hamiltonian four-fermion operators with overlap fermions
The renormalization of the most general dimension-six four-fermion operators without power subtractions is studied at one loop in lattice perturbation theory using overlap fermions. As expected,

Chiral symmetry, quark mass, and scaling of the overlap fermions
TLDR
The chiral symmetry relation and scaling of the overlap fermions are studied numerically on the quenched lattices at 3 couplings with about the same physical volume and the critical slowing down sets in abruptly at a very small quark mass close to those of the physical u and d quarks.
Transversely polarized parton densities, their evolution and their measurement
AbstractThe transverse spin asymmetry of a quark in a baryon and the linear polarization of a gluon in a vector meson are studied from thet-channel point of view. Using the Altarelli-Parisi approach,
