Parton distribution functions from lattice QCD
Martha Constantinou, Krzysztof Cichy
Parton distribution functions (PDFs) provide one of the most direct ways to describe the partonic structure of hadrons in QCD. They encode nonperturbative information about quarks,…
Generalized parton distributions from lattice QCD
Krzysztof Cichy, Martha Constantinou
This chapter gives an overview of the recent progress in extracting generalized parton distributions from lattice QCD. We briefly recall the theoretical principles of GPDs and expl…
Mellin Moments of Pion and Kaon Unpolarized PDFs from Nonlocal Operators in Lattice QCD
Joshua Miller, Joseph Torsiello, Krzysztof Cichy +2
We present a first-principles lattice-QCD determination of Mellin moments of the unpolarized pion and kaon parton distribution functions using matrix elements of boosted mesons cou…
Mellin Moments of the Unpolarized Gluon PDF in the Proton from Nonlocal Operators in Lattice QCD
Joseph Delmar, Krzysztof Cichy, Martha Constantinou +1
We present a lattice QCD determination of the Mellin moments of the unpolarized gluon parton distribution function in the proton. The analysis is based on matrix elements of nonloc…
Pion and Kaon PDFs from Lattice QCD via Large Momentum Effective Theory and Short-Distance Factorization
Joshua Miller, Joseph Torsiello, Isaac Anderson +4
In this work, we present a first-principles lattice-QCD calculation of the unpolarized quark PDF for the pion and the kaon. The lattice data rely on matrix elements calculated for…
Collins-Soper Kernel and Reduced Soft Function in Lattice QCD
Constantia Alexandrou, Simone Bacchio, Krzysztof Cichy +5
We evaluate the Collins-Soper kernel and the reduced soft function in lattice QCD, incorporating matching corrections. The calculation relies on the evaluation o…
