Abstract
Inspired by the evidence of the odderon exchange recently observed by the D0 and TOTEM Collaborations, a quantum chromodynamics (QCD) sum rule investigation is performed to study the odderon as a three-gluon bound state. There may exist six lowest-lying three-gluon odderons with the quantum numbers ${J}^{PC}=1/2/{3}^{\ifmmode\pm\else\textpm\fi{}\ensuremath{-}}$. We systematically construct their interpolating currents, and calculate their mass spectra. To verify their existence, we propose to search for the spin-3 odderons in their $VVV$ and $VVP$ decay channels directly at LHC, with $V$ and $P$ light vector and pseudoscalar mesons respectively.
