Spin resummation of heavy quarkonium photoproduction: from the gluonic gravitational form factors to the holographic pomeron
Kiminad A. Mamo, Kemal Tezgin, Christian Weiss
Exclusive heavy quarkonium photoproduction probes the proton's gluonic structure from near-threshold (fixed-spin exchanges, gravitational form factors) to high energies (reggeized…
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…
Holographic Open/Closed Exchange in Double Deeply Virtual Compton Scattering: Fixed- Structural Matching to the -Basis Wilson Kernels
Kiminad A. Mamo
We show that fixed-- holographic double deeply virtual Compton scattering (DDVCS), and its DVCS limit, give a fixed-scale structural match to the singlet conformal-OPE Wilson-ke…
From Vacuum to Nucleon: Fixed- Kernel Matching of Holographic Current Correlators to QCD
Kiminad A. Mamo
We show that the normalized non-normalizable photon profile fixed by the vacuum vector-current two-point function, when inserted into the fixed- hadronic Witten diagram, produce…
Momentum-projected hadron entanglement from lattice-QCD replica correlators
Kiminad A. Mamo
We define a finite-volume lattice-QCD density-matrix observable for the vacuum-subtracted spatial R'enyi response of a source-sink-prepared, momentum-projected hadron. At fixed reg…
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…
