  In this paper we show that the intrinsic heavy-quark QCD mechanism for the
hadroproduction of heavy hadrons at large $x_F$ can resolve the apparent
conflict between measurements of double-charm baryons by the SELEX fixed-target
experiment and the LHCb experiment at the LHC collider. We show that both
experiments are compatible, and that both results can be correct. The observed
spectroscopy of double-charm hadrons is in agreement with the predictions of
supersymmetric light front holographic QCD.
