Squeezed States and Particle Production in High Energy Collisions
  Using the `quantum optical approach' we propose a model of multiplicity distributions in high energy collisions based on squeezed coherent states.   We show that the k-mode squeezed coherent state is the most general one in describing hadronic mulitiplicity distributions in particle collision processes, describing not only $p \bar p$ collisions but $e^{+}e^{-}$, $\nu p$ and diffractive collisions as well.   The reason for this phenomenological fit has been gained by working out a microscopic theory in which the squeezed coherent sources arise naturally if one considers the Lorentz squeezing of hadrons and works in the covariant phase space formalism .
