  We show that cotunneling in the 5/2 fractional quantum Hall regime allows us
to test the Moore-Read wave function, proposed for this regime, and to probe
the nature of the fractional charge carriers. We calculate the cotunneling
current for electrons that tunnel between two quantum Hall edge states via a
quantum dot and for quasiparticles with fractional charges e/4 and e/2 that
tunnel via an antidot. While electron cotunneling is strongly suppressed, the
quasiparticle tunneling shows signatures characteristic of the Moore-Read
state. For comparison, we also consider cotunneling between Laughlin states,
and find that electron transport between Moore-Read states and between Laughlin
states at filling factor 1/3 have identical voltage dependences.
