We use the holographic construction to identify the pseudovector glueball with the Kalb-Ramond field, minimally coupled to bulk Dirac fermions. We derive the holographic C-odd form factor and its respective charge radius. Using the pertinent Witten diagrams, we derive and analyze the differential photoproduction cross section for $\\eta_{c,b}$ in the threshold regime, including the interference from the dual bulk photon exchange with manifest vector dominanc","authors_text":"Florian Hechenberger, Ismail Zahed, Kiminad A.
