Beaming Effect in Fermi Blazars
  The \gamma-ray loud blazars (flat spectrum radio quasars--FSRQs and BL
Lacertae objects-BLs) are very bright in the \gamma-ray bands, which is perhaps
associated with a beaming effect. Therefore, one can expect that the \gamma-ray
luminosity is correlated with the beaming factor. In this paper, we
investigated the relation between the radio Doppler factors and the gamma-ray
luminosities. Our analysis suggests that the \gamma-ray luminosity be strongly
correlated with the factor of \delta_R for the whole sample, FSRQs, and BLs.
When the effect of a common redshift is excluded, the correlation still exists
for the FSRQs sub-sample suggesting that the \gamma-rays are strongly beamed.
However, the partial correlation analysis does not show a correlation for the
small BL Lac sample.
