The Collins-Soper kernel from a vacuum soft function
Anthony Francis, C. -J. David Lin, Wayne Morris +1
The Collins-Soper kernel is calculated from a vacuum soft function using space-like Wilson lines with complex-directional vectors on the Euclidean lattice. Our pure gauge calculati…
Lattice extraction of the Collins-Soper kernel using the auxiliary field representation of the Wilson line
Anthony Francis, C. -J. David Lin, Wayne Morris +1
The Collins-Soper (CS) kernel may be obtained through the TMD soft function by formulating the Wilson line in terms of 1-dimensional auxiliary fermion fields on the lattice. Our co…
Parton physics from a heavy-quark operator product expansion: Dynamical lattice QCD calculation of moments of the pion and kaon light-cone distribution amplitudes
S. -P. Alex Chang, William Detmold, Anthony V. Grebe +5
The light-cone distribution amplitude (LCDA) is a fundamental non-perturbative quantity for understanding hadron structure and exclusive scattering processes. We report on our calc…
Extracting the distribution amplitude of pseudoscalar mesons using the HOPE method
S. -P. Alex Chang, William Detmold, Anthony V. Grebe +4
The pseudoscalar meson light-cone distribution amplitudes (LCDAs) are essential non-perturbative inputs for a range of high-energy exclusive processes in quantum chromodynamics. In…
Measurement of the TMD soft function on the lattice using the auxiliary field representation of the Wilson line
Anthony Francis, Issaku Kanamori, C. -J. David Lin +2
The transverse momentum dependent (TMD) soft function and Collins-Soper (CS) kernel may be obtained by formulating the Wilson line in terms of auxiliary one-dimensional fermion fie…
The lattice extraction of the TMD soft function using the auxiliary field representation of the Wilson line
Anthony Francis, Issaku Kanamori, C. -J. David Lin +2
The TMD soft function can be obtained by formulating the Wilson line in terms of auxiliary 1-dimensional fermion fields on the lattice. In this formulation, the directional vector…
Lattice QCD Constraints on the Fourth Mellin Moment of the Pion Light Cone Distribution Amplitude using the HOPE method
William Detmold, Anthony V. Grebe, Issaku Kanamori +3
The light-cone distribution amplitude (LCDA) of the pion contains information about the parton momentum carried by the quarks and is an important theoretical input for various pred…
