Gluon GTMD at strong coupling: fixed-spin saddle factorization and Reggeization
Kiminad A. Mamo, Ismail Zahed
Generalized transverse-momentum-dependent parton distributions (GTMDs) are the most complete two-parton correlation functions in QCD, encoding the joint spatial and momentum struct…
String-based axial and helicity-flip GPDs: a comparison to lattice QCD
Florian Hechenberger, Kiminad A. Mamo, Ismail Zahed
We construct an analytic, string based representation of the nucleon's axial and helicity flip conformal moments of generalized parton distributions that holds for any skewness and…
Rapidity-Dependent Spin Decomposition of the Nucleon
Florian Hechenberger, Kiminad A. Mamo, Ismail Zahed
We show that the two-dimensional Fourier transform of the generalized parton distributions (GPDs) has two distinct interpretations: at zero skewness () it yields the familiar…
Parametrization of GPDs from t-channel string exchange in AdS spaces
Kiminad A. Mamo, Ismail Zahed
We introduce a string-based parametrization for nucleon quark and gluon generalized parton distributions (GPDs) that is valid for all skewness. Our approach leverages conformal mom…
String-based parametrization of nucleon GPDs at any skewness: a comparison to lattice QCD
Kiminad A. Mamo, Ismail Zahed
We introduce a string-based parametrization for nucleon quark and gluon generalized parton distributions (GPDs) valid at all skewness values. The conformal moments of the GPDs are…
