We measure the clustering of over 55,000 quasars at redshifts 2.2 < z
< 3.4 drawn from the final sample of the Baryonic Oscillation
Spectroscopic Survey (BOSS). This is by far the largest sample ever used
to study quasar clustering at "intermediate" redshifts. We ameliorate
the effect of observational systematics on our clustering analyses by
weighting our control catalogues of random points by maps of how
observational systematics correlate with the BOSS quasar target density.
We find that there is no significant evolution in the quasar correlation
length and bias over our studied redshift range, implying that the
masses of the dark matter halos that host quasars decreases slightly
from z~2.2 to z~3.4. Our result also contradicts a monotonic relation
between the optical luminosity of quasars near redshift 2.5 and their
host halo masses. To begin to study whether this contradiction holds for
quasars' bolometric luminosity, we use data from the Wide-field Infra
red Survey Explorer (WISE) to study whether the luminosity or detection
of BOSS quasars in the mid-IR is correlated with the masses of quasars'
host halos. This work was partially supported by NSF award 1211112.
