Charged particles (h(+/-)) and K(0) mesons have been studied in photoproduced events containing at least one jet of E(T) > 8 GeV in a pseudorapidity interval (-0.5, 0.5) in the ZEUS laboratory frame. Distributions are presented in terms of transverse momentum, pseudorapidity and distance of the particle from the axis of a jet. The properties of h(+/-) within the jet are described well using the standard settings of PYTHIA, but the use of the multiparton interaction option improves the description outside the jets.
