Measurement of the TMD soft function on the lattice using the auxiliary field representation of the Wilson line Open
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 fields on the lattice. Our computation takes place in the regi…

Toward the determination of the gluon helicity distribution in the nucleon from lattice quantum chromodynamics Open
We present the first exploratory lattice quantum chromodynamics (QCD) calculation of the polarized gluon Ioffe-time pseudodistribution in the nucleon. The Ioffe-time pseudodistribution provides a frame-independent and gauge-invariant frame…

Non-singlet quark helicity PDFs of the nucleon from pseudo-distributions Open
The non-singlet helicity quark parton distribution functions (PDFs) of the nucleon are determined from lattice QCD, by jointly leveraging pseudo-distributions and the distillation spatial smearing paradigm. A Lorentz decomposition of appro…

Investigating Gluonic Operators in Coordinate Space Open
In this dissertation, a method of extracting gluon momentum distributions inside hadrons, and particularly nucleons, is developed. In general, the utility and application of performing calculations in coordinate space at the operator level…

The invisible moats of the Mun River Valley, NE Thailand: The examination of water management devices at mounded sites through ground penetrating radar (GPR) Open
The Mun River valley is well known for its moat-bound mounded archaeological sites that are usually associated with Iron Age occupation (~500BC- AD500). The investigation of these sites has provided a wealth of information on the changing …
