Abstract:
Charged particle production has been measured in Deep Inelastic Scattering (DIS) events using the ZEUS detector over a large range of Q2 from 10 to 1280 GeV2. The evolution with Q of the charged multiplicity and scaled momentum has been investigated in the current fragmentation region of the Breit frame. The data are used to study QCD coherence effects in DIS and are compared with corresponding e+e- data in order to test the universality of quark fragmentation. © 1995 Springer-Verlag.Neutral strange particle production in deep inelastic scattering at HERA

Abstract:
This paper presents measurements of K0 and Λ production in neutral current, deep inelastic scattering of 26.7 GeV electrons and 820 GeV protons in the kinematic range 102<640 GeV2, 0.00030.04. Average multiplicities for K0 and Λ production are determined for transverse momenta p T >0.5 GeV and pseudorapidities |η|<1.3. The multiplicities favour a stronger strange to light quark suppression in the fragmentation chain than found in e+e- experiments. The production properties of K0' s in events with and without a large rapidity gap with respect to the proton direction are compared. The ratio of neutral K0' s to charged particles per event in the measured kinematic range is, within the present statistics, the same in both samples. © 1995 Springer-Verlag.
