abstract = {Background: Energetic quarks in nuclear deep-inelastic
scattering propagate through the nuclear medium. Processes
that are believed to occur inside nuclei include quark
energy loss through medium-stimulated gluon bremsstrahlung
and intranuclear interactions of forming hadrons. More data
are required to gain a more complete understanding of these
effects.Purpose: To test the theoretical models of parton
transport and hadron formation, we compared their
predictions for the nuclear and kinematic dependence of pion
production in nuclei.Methods: We have measured charged-pion
production in semi-inclusive deep-inelastic scattering off
D, C, Fe, and Pb using the CLAS detector and the CEBAF
5.014-GeV electron beam. We report results on the
nuclear-to-deuterium multiplicity ratio for π+ and π− as
a function of energy transfer, four-momentum transfer, and
pion energy fraction or transverse momentum—the first
three-dimensional study of its kind.Results: The π+
multiplicity ratio is found to depend strongly on the pion
fractional energy z and reaches minimum values of
0.67±0.03, 0.43±0.02, and 0.27±0.01 for the C, Fe, and Pb
targets, respectively. The z dependencies of the
multiplicity ratios for π+ and π− are equal within
uncertainties for C and Fe targets but show differences at
the level of $10\%$ for the Pb-target data. The results are
qualitatively described by the GiBUU transport model, as
well as with a model based on hadron absorption, but are in
tension with calculations based on nuclear fragmentation
functions.Conclusions: These precise results will strongly
constrain the kinematic and flavor dependence of nuclear
effects in hadron production, probing an unexplored
kinematic region. They will help to reveal how the nucleus
reacts to a fast quark, thereby shedding light on its color
structure and transport properties and on the mechanisms of
the hadronization process.},
