Gottfried-Jackson polarization filters for holographic dilaton and transverse-traceless gluon responses in near-threshold photoproduction
Arkadiy I. Syamtomov
Within the Hatta-Yang holographic graviton-dilaton amplitude for near-threshold photoproduction, we identify exact dilaton-null spin-projection channels in the Gottfried-Jack…
From cross-section degeneracies to phase-sensitive observables in near-threshold J/psi production
Arkadiy I. Syamtomov
Near-threshold production is sensitive to scalar and traceless spin-two chromoelectric structure in the nucleon. We study whether present integrated and differential measurem…
QCD-Matched Gluonic Response in Heavy-Quarkonium Born-Oppenheimer EFT: Locality, Channel Factorization, and the Peskin Limit
Arkadiy I. Syamtomov
We formulate a source-dependent QCD-to-BOEFT matching for the gluonic response of a stable compact heavy-quarkonium state. The matched complementary-space resolvent preserves coupl…
Complex chromoelectric polarizability of a heavy-quarkonium resonance: pole definition and channel-complete pNRQCD matching
Arkadiy I. Syamtomov
For a stable compact quarkonium, chromoelectric polarizability is generated by two E1 transitions through virtual color-octet states. An unstable quarkonium is instead defined by a…
Chromoelectric and chromomagnetic matching to scalar and spin-two nucleon structure
Arkadiy I. Syamtomov
Compact heavy quarkonium couples through the multipole interaction to scalar and spin-two gluonic operators. At leading chromoelectric order the corresponding matching coefficients…
Light-front diagnostics in the 't Hooft model: II. Boundary cancellations, ERBL spectral sums, and analyticity of the EMT form factor
Arkadiy I. Syamtomov
A diagonal light-front overlap contains near-forward energy-momentum-tensor (EMT) information but is not itself a local matrix element. In the large- 't Hooft model we complet…
