  We provide details of a shorter letter and cond-mat/9702098 and some new
results. We describe a Chern-Simons theory for the fractional quantum Hall
states in which magnetoplasmon degrees of freedom enter. We derive correlated
wavefunctions, operators for creating quasiholes and composite fermions and
bosons (which are electrons bound to zeros). We show how the charge of these
particles and mass gets renormalized to the final values and compute the
effective mass approximately. By deriving a hamiltonian description of the
composite fermions and bosons and their charge and current operators, we make
precise and reconcile many notions that have been associated with them.
