Using recently published HERMES data on multiplicities in semi-inclusive deep-inelastic scattering, we discuss the flavor dependence of unpolarized transverse-momentum dependent distribution and fragmentation functions. We find convincing indications that favored fragmentation into pions have smaller average transverse momentum than unfavored ones and fragmentation into kaons. We find weaker indications of flavor dependence in the transverse-momentum dependence of parton distributions.

We calculate the transverse momentum dependence of back-to-back production of one hadron and one jet in electron-positron annihilation, i.e., e+e- → h jet X, at Q2 = 100 GeV2. We use the parameters of the transverse-momentum-dependent (TMD) fragmentation functions we recently extracted from HERMES data at 2.4 GeV2. We apply TMD evolution according to two different approaches and using different parameters for the so-called nonperturbative part of TMD evolution. We discuss the differences in our predictions and how experimental measurements could discriminate between different implementations of TMD evolution and different choices of nonperturbative parameters.
