Description:
  'The production of prompt $D^0$ mesons in proton-lead collisions in both the forward and backward rapidity regions at a center-of-mass energy per nucleon pair of $\sqrt{s_{NN}} = 8.16\,\mathrm{TeV}$ is measured by the LHCb experiment. The nuclear modification factor of prompt $D^0$ mesons is determined as a function of the transverse momentum $p_\mathrm{T}$, and the rapidity in the nucleon-nucleon center-of-mass frame $y^\ast$. In the forward rapidity region, significantly suppressed production with respect to $pp$ collisions is measured, which provides significant constraints on models of nuclear parton distributions and hadron production down to the very low Bjorken-$x$ region of $\sim\! 10^{-5}$. In the backward rapidity region, a suppression with a significance of $2.0\! -\! 3.8$ standard deviations compared to parton distribution functions in a nuclear environment expectations is found in the kinematic region of $p_\mathrm{T} > 6\,\mathrm{GeV}/c$ and $-3.25 < y^\ast < -2.5$, corresponding to $x\sim 0.01$.'
