Connecting Heavy-Quarkonium Born-Oppenheimer EFT to the Peskin OPE
Arkadiy I. Syamtomov
We formulate a source-dependent QCD-to-BOEFT matching for the gluonic response of a normalized stable compact heavy-quarkonium state. A gauge-covariant complementary-space resolven…
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…
Near-Threshold OPE Constraints and High-Energy Diffractive Dynamics in J/psi Photoproduction
Arkadiy I. Syamtomov
The paper studies exclusive J/ψ photoproduction near the production threshold using leading‑twist Coulombic OPE with target‑mass resummation and fits to recent GlueX and CLAS12 dat…
Light-front transverse profiles of scalar and spin-two chromoelectric EMT responses in near-threshold charmonium probes
Arkadiy I. Syamtomov
I construct light-front transverse profile functions for the scalar and spin-two chromoelectric energy-momentum-tensor responses selected by compact-charmonium probes of the proton…
