  We study in this paper the properties of a gas of fermions interacting {\em
via} a scalar potential $v(q)=4\pi{e}^2/q^2$ for $q<\Lambda<<k_F$ at dimensions
larger than one, where $\Lambda$ is a high momentum cutoff and $k_F$ is the
fermi wave vector. In particular, we shall consider the $e^2\to\infty$ limit
where the potential becomes confining. Within a bosonization approximation,
effective Hamiltonians describing the low energy physics of the system are
constructed, where we show that the system can be described as a fermi liquid
formed by chargeless quasi-particles which has vanishing wavefunction overlap
with the bare fermions in the system.
