  The calculations based on the next-to-leading logarithm (NLL) approximation
for the Balitsky-Fadin-Kuraev-Lipatov (BKFL) evolution are presented for the
Mueller-Navelet (MN) dijet production cross section, as well as for their
ratios at different collision energies. The MN dijet denotes the jet pair
consists of jets, which were selected with $p_{\perp} > p_{\perp\min}$ and with
maximal rapidity separation in the event. The NLL BFKL predictions for the MN
cross sections are given for the $pp$ collisions at $\sqrt{s}=2.76$, $8$, and
$13$ TeV, for $p_{\perp\min} = 20$ and $35$ GeV. The results are in agreement
with the measurement by the CMS experiment in $pp$ collisions at
$\sqrt{s}=2.76$ TeV and $p_{\perp\min} = 35$ GeV within the theoretical and
experimental uncertainties. The predictions of the NLL BFKL calculation of
ratios of the MN cross sections at different collision energies and
$p_{\perp\min}$ are also presented.
