Abstract
We study theoretically the dispersion of a single quasiparticle or quasihol e of the fractional quantum Hall effect, obtained by injecting or removing a composite fermion. By comparing to a free fermion system, we estimate the regime of validity of the Landau Fermi-liquid-type description and deduce the Landau mass.
