Treating the light-flavor constituent quarks and antiquarks whose momentum information is extracted from the data of soft light-flavor hadrons inppcollisions atTeV as the underlying source of chromatically neutralizing the charm quarks of low transverse momenta (), we show that the experimental data ofspectra of single-charm hadrons,,andat mid-rapidity in the lowrange (GeV/c) inppcollisions atTeV can be well understood by the equal-velocity combination of perturbatively created charm quarks and those light-flavor constituent quarks and antiquarks. This suggests a possible new scenario of lowcharm quark hadronization, in contrast to the traditional fragmentation mechanism, inppcollisions at LHC energies. This is also another support for the exhibition of the soft constituent quark degrees of freedom for the small parton system created inppcollisions at LHC energies.
