Query: Odd spin glueball masses and the odderon Regge trajectories from the
  holographic hardwall model   We use the holographic hardwall model to calculate the masses of light
glueball states with odd spin and P= C= -1 associated with odderons.
Considering Dirichlet and Neumann boundary conditions we obtain expressions for
the odderon Regge trajectories consistent with those calculated using other
approaches.
