  With the advent of TeV-energy colliding machines, such as the Large Hadron
Collider (LHC), the possibility has opened up to test predictions of Quantum
Chromodynamics (QCD) and, more in general, of the Standard Model (SM), in new,
and so far unexplored, kinematical regimes. Among the many reactions that can
be investigated at LHC, the Higgs production is one of the most important and
challenging for the entire high-energy physics Community. Beside usual studies
in the Higgs sector, it has recently been highlighted how differential Higgs
distributions can be effectively used as ``stabilizers'' of the high-energy
dynamics of QCD. The definition and the study of observables sensitive to
high-energy dynamics in Higgs production has the double advantage of (i)
allowing us to clearly disentangle the high-energy dynamics from the
fixed-order one and (ii) providing us with an auxiliary tool to extend Higgs
studies in wider kinematical regimes. In this work, we will show how a general
hybrid collinear/high energy factorization can be built up for the inclusive
production of a Higgs in association with a jet. Then, we will present some
phenomenological analyses that corroborate the underlying assumption that this
reaction can be used to investigate the semi-hard regime of QCD. Finally, we
will focus on more formal developments, such as the inclusion of subleading
corrections to previous studies, via the calculation of the forward
next-to-leading order Higgs impact factor.
