  We study the transverse momentum ($p_T$) spectrum of charged particles
produced in deep inelastic scattering (DIS) at small Bjorken $x$ in the central
region between the current jet and the proton remnants. We calculate the
spectrum at large $p_T$ with the BFKL $\ln (1/x)$ resummation included and then
repeat the calculation with it omitted. We find that data favour the former. We
normalize our BFKL predictions by comparing with HERA data for DIS containing a
forward jet. The shape of the $x$ distribution of DIS + jet data are also well
described by BFKL dynamics.
