  The distribution of linearly polarized gluons inside a large nucleus is
studied in the framework of the color glass condensate. We find that the
Weizs\"acker-Williams distribution saturates the positivity bound at large
transverse momenta and is suppressed at small transverse momenta, whereas the
dipole distribution saturates the bound for any value of the transverse
momentum. We also discuss processes in which both distributions of linearly
polarized gluons can be probed.
