Glueball gravitational form factors in dynamical holography

Kiminad A. Mamo

We present the first holographic study of gravitational form factors (GFFs) of scalar, pseudoscalar and canonical-spin-averaged tensor glueball targets. These observables test grav…

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 observable for the vacuum-subtracted spatial Rényi response of a source--sink-prepared, momentum-projected hadron. At fixed regulator, integer…

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…

Entanglement, Trace Anomaly and Confinement in QCD

Kiminad A. Mamo

We formulate confinement in QCD as an entropic surface phenomenon. Quark and gluon quantum information is localized on a transverse entangling two-sphere of radius ; at thi…
