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…
Momentum-projected hadron entanglement from lattice-QCD replica correlators
Kiminad A. Mamo
We define a finite-volume lattice-QCD observable for the vacuum-subtracted spatial Rényi response of a source--sink-prepared, momentum-projected hadron. At fixed regulator, integer…
String-based axial and helicity-flip GPDs: a comparison to lattice QCD
Florian Hechenberger, Kiminad A. Mamo, Ismail Zahed
