<b>Investigations into the Flavor Dependence of TMDs </b><br>
<br>
Recent experimental data on semi-inclusive deep-inelastic scattering
from the Hermes collaboration allow us to discuss for the first
time the flavor dependence of unpolarized transverse-momentum
dependent distribution and fragmentation functions. We find
convincing indications that favored fragmentation functions into
pions have smaller average transverse momentum than unfavored
functions and fragmentation functions into kaons. We find weaker
indications of flavor dependence in the distribution functions.<br>
