Generalized Parton Distributions from Lattice QCD with Asymmetric Momentum Transfer: Unpolarized Quarks at Nonzero Skewness
Min-Huan Chu, Manuel Colaço, Shohini Bhattacharya +4
We extend the formalism of asymmetric frames of reference for generalized parton distributions (GPDs) to the case of nonzero skewness, i.e., including longitudinal momentum transfe…

Four Gluon Vertex from Lattice QCD
Manuel Colaço, Orlando Oliveira, Paulo J. Silva
A lattice QCD calculation for the four gluon one-particle irreducible Green function in the Landau gauge is discussed. Results for some of the associated form factors are reported…

The four-gluon vertex in Landau gauge
Manuel Colaço, Orlando Oliveira, Paulo J. Silva
The Landau gauge four-gluon vertex is studied using high statistical lattice simulations for several momentum configurations. Furthermore, the outcome of the lattice QCD simulation…
