  The exclusive photoproduction of $\Upsilon$(1S), $\Upsilon$(2S) and
$\Upsilon$(3S) mesons is studied in their leptonic ($\mu^{+}\mu^{-}$) decay
modes, in ultraperipheral pPb collisions at $\sqrt{s_{NN}} = 5.02$ TeV. The
data was recorded by the CMS experiment corresponding to an integrated
luminosity of $32.6$ nb$^{-1}$. The differential cross-section for
$\Upsilon$(n) states (n=1,2,3), has been measured as a function of transverse
momentum squared $p_{T}^{2}$, and rapidity $y$. The $\Upsilon$(1S)
photoproduction cross-section is extracted in the region $|y|<2.2$ as a
function of the photon-proton centre-of-mass energies $W_{\gamma p}$, in the
range $91 <W_{\gamma p}< 826$ GeV. The measurements are compared to theoretical
predictions and to previous measurements.
