Query: Analyticity of the Scattering Amplitude, Causality and High-Energy
  Bounds in Quantum Field Theory on Noncommutative Space-Time   In the framework of quantum field theory (QFT) on noncommutative (NC)
space-time with the symmetry group $O(1,1)\times SO(2)$, we prove that the
Jost-Lehmann-Dyson representation, based on the causality condition taken in
connection with this symmetry, leads to the mere impossibility of drawing any
conclusion on the analyticity of the $2\to 2$-scattering amplitude in
$\cos\Theta$, $\Theta$ being the scattering angle. Discussions on the possible
ways of obtaining high-energy bounds analogous to the Froissart-Martin bound on
the total cross-section are also presented.
