  We calculate the Fermi energy dependence of the (time-averaged) current and
shot noise in an impurity-free carbon bilayer (length $L\ll$ width $W$), and
compare with known results for a monolayer. At the Dirac point of charge
neutrality, the bilayer transmits as two independent monolayers in parallel:
Both current and noise are resonant at twice the monolayer value, so that their
ratio (the Fano factor) has the same 1/3 value as in a monolayer -- and the
same value as in a diffusive metal. The range of Fermi energies around the
Dirac point within which this pseudo-diffusive result holds is smaller,
however, in a bilayer than in a monolayer (by a factor $l_{\perp}/L$, with
$l_{\perp}$ the interlayer coupling length).
