  We investigate lepton-pair production in hard exclusive hadron-hadron
collisions.
  We consider a double handbag (DH) mechanism in which the process amplitude
factorizes in hard subprocesses, qq -> qq gamma* and qg -> qg gamma*, and in
soft hadron matrix elements parameterized as generalized parton distributions
(GPDs). Employing GPDs extracted from exclusive meson electroproduction, we
present predictions for the lepton-pair cross section at kinematics typical for
the LHC, NICA and FAIR. It turns out from our numerical studies that the
quark-gluon subprocess dominates by far, the quark-quark (antiquark)
subprocesses are almost negligible.
