Determine the Odderon trajectory intercept

Determine the intercept of the leading $C=-1$ glueball trajectory associated with the Odderon.

Background

The Odderon is identified with the leading $C=-1$ counterpart of the Pomeron and, in a constituent picture, with three-gluon exchange. Its trajectory is relevant both to the spectrum of negative-charge-conjugation glueballs and to high-energy $pp$ and $p\bar p$ scattering. Existing calculations predict an intercept below unity, while experimental interpretations of scattering data have been taken as evidence for Odderon exchange. The paper explicitly identifies the intercept itself as unresolved.
