Prompt Photons and Particle Momentum Distributions at HERA

Recent results, obtained by the H1 and ZEUS collaborations, are presented on differential cross sections, for inclusive prompt photon production in DIS and for photoproduction of prompt photons accompanied by a hadronic jet. Also presented are cross sections of normalised scaled momentum distribution of charged final state hadrons, measured by H1 in DIS $ep$ collisions at high $Q^2$ in the Breit frame of reference.
