A new state of matter, where gluons have overlapping wave functions, has
been in the minds of particle and nuclear physicists for decades. This
gluon saturated state could explain several recent observations such as
particle production and collectivity observed in p+p, p+A and A+A
collisions at RHIC and LHC.

The LHCb experiment is a forward spectrometer with vertexing, tracking,
$p$, $K$, $pi$, $e$, $\mu$ identification and calorimetry in the
pseudorapidity region $2< \eta <5$. LHCb is therefore well suited to
study the gluon density of hadrons in at small Bjorken-x values ($x \sim 10^{-6}-10^{-5}$), down to two orders of magnitude smaller than HERA.

The status of the analysis efforts aimed at finding the gluon saturation
scale at LHCb using isolated photon yields and their correlations with
hadrons and jets will be shown. In addition, the concept and R&D efforts
of a new particle tracker inside the LHCb magnet to improve measurements
of small $Q^2$ processes, where gluon saturation is expected, will be
