Lattice QCD Study of Transverse-Momentum Dependent Soft Function

Yuan Li et al.

Summary: In this work, we study the intrinsic, rapidity-independent soft function within the framework of large momentum effective theory using lattice QCD. After renormalization and removal of higher-twist contamination, we obtain an intrinsic soft function that is comparable to the one-loop perturbative result at large external momentum. Determining the nonperturbative soft function from first principles is crucial for our understanding of processes with small transverse momentum.

QCD factorization of quasi generalized quark distributions

J. P. Ma et al.

Summary: We study the factorization of quasi generalized quark distributions with twist-2 generalized parton distributions using a different approach. We derive the factorization relations of all quasi generalized quark distributions at one-loop, including the contributions from twist-2 generalized gluon distributions. Our results apply to hadrons with different spins, not only to spin-1/2 hadrons.

Transversity parton distribution function of the nucleon using the pseudodistribution approach

Colin Egerer et al.

Summary: We determined the nonsinglet transversity parton distribution function (PDF) of the nucleon using lattice quantum chromodynamics. By analyzing the short-distance behavior and using the matching coefficients, we extracted the transversity PDF and studied its x-dependence through an expansion in Jacobi polynomials. Comparing our estimate with global fit results based on single transverse spin asymmetry, we found that the nucleon sea is isospin symmetric with respect to transversity.

Summary: In this article, the heavy-quark operator product expansion method is numerically implemented for the first time to determine the second Mellin moment of the pion LCDA. The resulting value, obtained at a pion mass of 550 MeV and a factorization scale of 2 GeV in quenched QCD, is 0.210 +/- 0.013(stat) +/- 0.034(sys), which is compatible with previous determinations of this quantity.

Generalized parton distributions from the off-forward Compton amplitude in lattice QCD

A. Hannaford-Gunn et al.

Summary: In this study, the properties of generalized parton distributions (GPDs) are determined from a lattice QCD calculation of the off-forward Compton amplitude (OFCA). By extending the Feynman-Hellmann relation to second-order matrix elements at off-forward kinematics, the OFCA can be calculated from lattice propagators computed in the presence of a background field. Using an operator product expansion, the deeply virtual part of the OFCA is parametrized in terms of the low-order Mellin moments of the GPDs. Numerical investigations are conducted to determine the form factors of the lowest two moments of the nucleon GPDs at zero-skewness kinematics. This study provides novel constraints on the x- and t-dependence of GPDs and demonstrates the viability of calculating the OFCA from first principles.

Parton distributions and lattice-QCD calculations: Toward 3D structure

Martha Constantinou et al.

Summary: The theory of quantum chromodynamics (QCD) describes the strong force binding hadrons together. Parton distribution functions (PDFs) have been successful in describing collinear partons within hadrons, but new experiments are exploring the transverse structure using generalized parton distributions (GPDs) and transverse-momentum-dependent parton distribution functions (TMD PDFs). Different methods, including perturbative QCD factorization theorems and lattice-QCD calculations, are used to determine PDFs and generalize the understanding of hadron structure.

A hybrid renormalization scheme for quasi light-front correlations in large-momentum effective theory

Xiangdong Ji et al.

Summary: In LaMET, parton physics in hadrons of momentum Pz is calculated by computing coordinate-space-z correlation functions that need proper renormalization to deal with linear and logarithmic divergences in lattice spacing. A hybrid renormalization procedure is introduced to match lattice correlations to those in the continuum MS scheme without introducing non-perturbative effects. Extrapolating lattice data to the asymptotic z-region based on generic properties of coordinate space correlations at moderate and large Pz is recommended to obtain momentum-space distributions.

Summary: In this study, the Distillation spatial smearing program was applied to improve the extraction of the unpolarized isovector valence PDF of the nucleon. By analyzing the matched ITD and directly matching the pITD to the PDF, a concerning deviation and DGLAP evolution were observed. The utility of distillation in such structure studies was further highlighted through observation and correction of this discrepancy.

Summary: This study presents the first lattice QCD calculation of the distribution amplitudes of longitudinally and transversely polarized vector mesons K* and phi using large momentum effective theory.

Summary: The large-momentum effective theory (LaMET) offers a new way to extract parton physics from proton properties through Lorentz symmetry. It provides an alternative to the standard formalism of partons by allowing for the extraction of various partonic observables through effective field theory matching and running. Future lattice QCD calculations could further enhance our understanding of hadronic structure and experimental data related to proton parton distribution.
