  The study of the production of two forward jets with a large interval of
rapidity at hadron colliders was proposed by Mueller and Navelet as a possible
test of the high energy dynamics of QCD. We analyze this process within a
complete next-to-leading logarithm framework, supplemented by the use of the
Brodsky-Lepage-Mackenzie procedure extended to the perturbative Regge dynamics,
to find the optimal renormalization scale. This leads to a very good
description of the recent CMS data at LHC for the azimuthal correlations of the
jets.
