Dear Lamiaa, I send here the abstract that I want to submit for the October
APS.

*Charged-pion multiplicity ratio and EMC effect in e-A DIS with CLAS*We
present a measurement of charged-pion production in DIS off 2H, C, Fe, and
Pb using the CLAS detector and the CEBAF 5 GeV electron beam. We report a
triple-differential measurement of the multiplicity ratio for $\pi^{+}$ and
$\pi^{-}$ as a function of virtual-photon energy and virtuality, and pion
momentum fraction or transverse momentum. The results are compared with the
GiBUU transport model, nuclear fragmentation functions, as well as with a
model based on pre-hadron absorption. Also we report results for the EMC
ratio that extends previous measurements to lower Q2 and compare with
expectations from nuclear PDFs. These precise results could help constrain
the flavour dependence of nuclear effects and probe an unexplored kinematic
region where the hadronization timescales are expected to be of the same
order as the nuclear lengths.

Best regards.
Sebastián.
