We investigate the possibility to detect the scalar Higgs boson decay in the associated
and
production at the LHC using the
-factorization QCD approach. Our consideration is based on the off-shell (i.e. depending on the transverse momenta of initial quarks and gluons) production amplitudes of
,
, and
partonic subprocesses supplemented with the Catani–Ciafoloni–Fiorani–Marchesini (CCFM) dynamics of parton densities in a proton. We argue that the
signal could be observed at large transverse momenta near the Higgs boson peak despite the overwhelming QCD background, and we point out the important role of angular correlations between the produced
boson and
-quarks.
