Contribution

It proposes a novel link between the Pomeron and glueball Regge trajectories, including a specific prediction of a tensor glueball mass.

Findings

Pomeron may be related to a glueball-based Regge trajectory

Predicted tensor glueball mass at 2.8 GeV

Connects phenomenological data with nonperturbative QCD

Abstract

It has long been believed that the Pomeron, which has been successful in phenomenological fits to high energy scattering data, is associated with gluonic exchange. By determining the Regge-nucleon vertex in terms of previously determined glueball-quark coupling we show that the Pomeron might be related to the Regge trajectory defined by a light scalar glueball/sigma system and a tensor glueball, which involves complicated nonperturbative QCD. We predict a tensor glueball at 2.8 GeV.
