Query: Dihadron Production at LHC: BFKL Predictions for Cross Sections and
  Azimuthal Correlations   A study of the inclusive production of a pair of hadrons (a "dihadron"
system), having high transverse momenta and separated by a large interval of
rapidity, is presented. This process has much in common with the widely
discussed Mueller--Navelet jet production and can be also used to access the
BFKL dynamics at proton colliders. Large contributions enhanced by logarithms
of energy can be resummed in perturbation theory within the BFKL formalism in
the next-to-leading logarithmic accuracy. The experimental study of dihadron
production would provide with an additional clear channel to test the BFKL
dynamics. The first theoretical predictions for cross sections and azimuthal
angle correlations of the two hadrons produced with LHC kinematics are
presented.
